• Does Deregulation Help? The Impact of Employment Protection Reforms on Youths’ Unemployment and Temporary Employment Risks in Europe

  2016

  European Sociological Review · 119 Zitationen · DOI

  Rigid employment protection legislation (EPL) has been blamed as the root of youths’ labour market integration problems in Europe. Many European countries have reacted by deregulating employment protection laws, often targeting youths as a group. However, doubts about the effectiveness of EPL reforms have arisen. Against this background, this article investigates whether EPL reforms succeeded in integrating youths into labour markets or whether they were ineffective and just promoted temporary employment as a crucial new social inequality in Europe. Based on two-step, three-level analyses using micro-data from the European Labour Force Survey for 19 European countries for the period from 1992 to 2012, our results show that deregulating the use of temporary contracts increased temporary employment risks of youths but did not reduce (for low-educated young men, even increased) unemployment risks. In contrast, we find some evidence that decreasing the protection of permanent jobs was successful in decreasing risks of inequality/insecurity (in terms of temporary jobs) without affecting the risks of labour market exclusion.

• Spatially resolved determination of dark saturation current and series resistance of silicon solar cells

  2009

  physica status solidi (RRL) - Rapid Research Letters · 117 Zitationen · DOI

  Abstract Luminescence images of silicon solar cells contain information about local recombination properties and local series resistance. It is difficult to separate the information and interpret single images correctly and quantitatively though, which greatly limits the use of single luminescence images, in particular for the application as an in‐production characterization tool. We therefore developed a fast method based on photoluminescence imaging for a spatially resolved coupled determination of the dark saturation current and series resistance (C‐DCR).

  Context effects, where a characteristic of an upper-level unit or cluster (e.g., a country) affects outcomes and relationships at a lower level (e.g., that of the individual), are a primary object of sociological inquiry. In recent years, sociologists have increasingly analyzed such effects using quantitative multilevel modeling. Our review of multilevel studies in leading sociology journals shows that most assume the effects of lower-level control variables to be invariant across clusters, an assumption that is often implausible. Comparing mixed-effects (random-intercept and slope) models, cluster-robust pooled OLS, and two-step approaches, we find that erroneously assuming invariant coefficients reduces the precision of estimated context effects. Semi-formal reasoning and Monte Carlo simulations indicate that loss of precision is largest when there is pronounced cross-cluster heterogeneity in the magnitude of coefficients, when there are marked compositional differences among clusters, and when the number of clusters is small. Although these findings suggest that practitioners should fit more flexible models, illustrative analyses of European Social Survey data indicate that maximally flexible mixed-effects models do not perform well in real-life settings. We discuss the need to balance parsimony and flexibility, and we demonstrate the encouraging performance of one prominent approach for reducing model complexity.

• Determination of local minority carrier diffusion lengths in crystalline silicon from luminescence images

  2009

  Journal of Applied Physics · 77 Zitationen · DOI

  In 2007 Würfel et al. [J. Appl. Phys. 101, 123110 (2007)] introduced a method to determine spatially resolved minority carrier diffusion lengths in silicon solar cells from electroluminescence intensity ratios. The key feature of this method was the exploitation of reabsorption of luminescence within a solar cell through optical short pass filters. The first part of this work deals with some experimental challenges which we encountered with the practical application of this method. A procedure of removing an artifact due to typical lateral filter inhomogeneities is introduced. Moreover, temperature dependence of luminescence is discussed and incorporated into the underlying model. The second part of this work aims at a determination of spatially resolved carrier diffusion lengths from photoluminescence (PL) on silicon wafers. The shortcomings of a diffusion length determination from PL intensity ratios are discussed. A straightforward method to determine spatially resolved integral excess charge carrier density from single PL images is introduced, thereby rendering a calibration with another measuring technique unnecessary. We show that quantitative information about recombination properties, such as minority carrier diffusion length, can be directly extracted from single PL images of silicon wafers.

• External labour market flexibility and social inequality

  2004

  European Societies · 67 Zitationen · DOI

  In this paper we examine the impact of temporary work on two dimensions of social inequality: income and career mobility. Additionally, we are taking a comparative perspective on this subject by comparing Germany and the UK. To investigate the effects of temporary work we use data from the German Socio-Economic Panel and the British Household Panel Study on non-self-employed respondents. The results show that temporary work does influence the system of social inequality: we found wage penalties and an increased probability of severe negative effects on the working careers of temporarily employed persons in both countries (net of education, age, and a variety of other covariates). Thus we can conclude that temporary employment represents a substantial socio-economic risk for employees. Most importantly, this holds true for both the German and the British case, two quite distinct labour market regimes.

• Minority carrier lifetime in silicon wafers from quasi-steady-state photoluminescence

  2010

  Applied Physics Letters · 62 Zitationen · DOI

  Based on quasi-steady-state photoluminescence, we present an approach to extract minority carrier lifetime from silicon wafers without a priori information about any material parameter (e.g., dopant concentration or mobility). A sinusoidal oscillation of irradiation of a silicon sample in time stimulates a likewise oscillating excess carrier density. Our approach is based on the fact that—in the quasi-steady-state regime—the time shift between the maxima of irradiation intensity and the intensity of radiative recombination is linked to effective minority carrier lifetime. Exploiting the continuity equation, it is possible to determine injection dependent minority carrier lifetime from there.

• Quantitative carrier lifetime measurement with micron resolution

  2010

  Journal of Applied Physics · 56 Zitationen · DOI

  In the last fifteen years the measurement of the spatially resolved carrier lifetime has emerged as a valuable tool for the characterization of silicon wafers and solar cells. In most of the available measurement methods, the spatial resolution is constrained to the order of several 10 to 100 μm by the diffusion length of the charge carriers. In this paper we introduce a contactless quantitative technique to determine the Shockley–Read–Hall lifetime with a spatial resolution of 1 μm. This technique is based on high injection microphotoluminescence spectroscopy and allows a quantitative analysis of microscopic defects such as grain boundaries and metal precipitates by virtue of the high spatial resolution.

• The Changing Wage Distribution in Germany between 1985 and 2006

  2009

  Schmollers Jahrbuch · 50 Zitationen · DOI

  In this paper the changes in the wage distribution in (West-)Germany between 1985 and 2006 are analysed. The theoretical framework is based on the literature on skill-biased technological change (SBTC) and on structural theory. Analyses draw on descriptive measures of the development of wage inequality among blue- and white-collar workers as well as on regression analyses of individual and structural determinants of wages for the years 1985 to 2006. The results show that wage inequality remained fairly constant until the early 1990s, but started to increase from the mid-1990s onwards. Moreover, regression analyses reveal that this increase was paralleled by rising inter-class wage differentials, while returns to (higher) education decreased.

• Spatially resolved determination of the dark saturation current of silicon solar cells from electroluminescence images

  2009

  Journal of Applied Physics · 49 Zitationen · DOI

  We present a novel method to determine spatially resolved the dark saturation current of standard silicon solar cells. For this two electroluminescence images are taken at two different voltages. From these two images, first the spatial voltage distribution can be calculated. Second by applying the Laplacian to the voltage image from Ohm’s law and the continuity equation, the current through the device at a certain position can be determined. Knowing the local current through the device, the local voltage, and the emitter sheet resistance allows to determine the local dark saturation current. The clue of this method is to cope with the noise by using an appropriate noise reduction algorithm. By simulating electroluminescence images with realistic noise and known dark saturation current we demonstrate the applicability of the method with our noise reduction algorithm. Experimentally we compare our method with spectral response light beam induced current on multicrystalline solar cell.

• Quality of work and job satisfaction: comparing female part-time work in four European countries

  2016

  International Review of Sociology · 47 Zitationen · DOI

  Adding to the debate on the integrative or marginalizing nature of female part-time work, this article provides a comparative analysis of the implications of female part-time work for different intrinsic job quality dimensions and job satisfaction. Drawing on national micro-data from Britain, Germany, the Netherlands, and Sweden, our multivariate analyses show cross-national similarities in terms of lower job learning opportunities for female part-timers. We found a significantly higher incidence of repetitiveness only among Swedish female part-timers and lower degrees of task discretion among British, Dutch, and Swedish women working part-time hours. Female part-timers were either equally satisfied with their work as female full-timers or even more satisfied. This held true also after accounting for the lower intrinsic job quality of part-time work. While women working part-time hours were as affected by their job quality characteristics as were full-timers, we conclude that the shorter hours of work per se provide an important additional source of job satisfaction.

• Separation of local bulk and surface recombination in crystalline silicon from luminescence reabsorption

  2009

  Progress in Photovoltaics Research and Applications · 44 Zitationen · DOI

  Abstract Spontaneous photoemission of crystalline silicon provides information on excess charge carrier density and thereby on electronic properties such as charge carrier recombination lifetime and series resistance. This paper is dedicated to separating bulk recombination from surface recombination in silicon solar cells and wafers by exploiting reabsorption of spontaneously emitted photons. The approach is based on a comparison between luminescence images acquired with different optical short pass filters and a comprehensive mathematical model. An algorithm to separate both front and back surface recombination velocities and minority carrier diffusion length from photoluminescence (PL) images on silicon wafers is introduced. This algorithm can likewise be used to simultaneously determine back surface recombination velocity and minority carrier diffusion length in the base of a standard crystalline silicon solar cell from electroluminescence (EL) images. The proposed method is successfully tested experimentally. Copyright © 2009 John Wiley & Sons, Ltd.

• Ökonomische Unsicherheit und Fertilität. Die Wirkung von Beschäftigungsunsicherheit und Arbeitslosigkeit auf die Familiengründung in Ost- und Westdeutschland / Economic Insecurity and Fertility. The Effects of Job Insecurity and Unemployment on Family Formation in East and West Germany

  2009

  Zeitschrift für Soziologie · 35 Zitationen · DOI

  Zusammenfassung Vor dem Hintergrund der jüngsten, teils kontroversen wissenschaftlichen Debatte zur Auswirkung ökonomischer Unsicherheit auf die Familiengründung analysieren wir in diesem Beitrag die Fertilitätskonsequenzen der zwei wohl wichtigsten Indikatoren ökonomischer Unsicherheit - befristeter Beschäftigungsverhältnisse und Arbeitslosigkeit - in Ost- und Westdeutschland. Basierend auf Daten des Sozio-oekonomischen Panels (SOEP) der Jahre 1995-2007 können wir weder für ost- noch für westdeutsche Frauen nachweisen, dass befristete Arbeitsverhältnisse zu einem Aufschub der ersten Mutterschaft führen. Ebenfalls lassen sich keine Wirkungsunterschiede befristeter Beschäftigung nach individuellem Bildungsniveau, dem Qualifikationsgrad der beruflichen Position oder dem Wirtschaftssektor feststellen. Phasen von Arbeitslosigkeit hingegen führen sowohl in Ost- als auch in Westdeutschland zu einer Verschiebung der ersten Geburt. Allerdings unterscheiden sich die Fertilitätsmuster zwischen Ost- und Westdeutschland dahingehend, dass in Westdeutschland Familiengründungen häufig dann verschoben werden, wenn der männliche Partner von Arbeitslosigkeit betroffen ist, während der Prozess der Familiengründung in Ostdeutschland weniger von der Erwerbssituation des männlichen Partners als vielmehr von der Arbeitsmarktlage der Frau betroffen zu sein scheint.

• Determination of Bulk Lifetime and Surface Recombination Velocity of Silicon Ingots From Dynamic Photoluminescence

  2013

  IEEE Journal of Photovoltaics · 34 Zitationen · DOI

  This paper elaborates upon the theory of self-consistent minority carrier bulk lifetime measurements of silicon ingots via time-modulated photoluminescence and presents an experimental proof of concept. For silicon ingots, the solution of the continuity equation at harmonic time modulation of excess carrier generation is shown to generally reveal a remarkably pronounced contrast with respect to minority carrier bulk lifetime. We combine our dynamic self-consistent approach with an analysis of surface recombination velocity from photoluminescence intensity ratios upon irradiation with different laser wavelengths. This combined analysis enables an accurate simultaneous determination of bulk lifetime and surface recombination velocity. For sufficiently high or accurately known ingot surface recombination velocities, this approach could likewise be used for an accurate determination of the minority carrier diffusion coefficient and of minority carrier mobility in novel silicon materials.

• Understanding and resolving the discrepancy between differential and actual minority carrier lifetime

  2013

  Journal of Applied Physics · 25 Zitationen · DOI

  Differential light-biased dynamic measurements of charge carrier recombination properties in semiconductors have long been known to yield only differential rather than actual recombination properties. Therefore, the determination of injection-dependent recombination properties from such measurements was previously found to require integration over the entire injection range. Recent investigations of the phase shift between a time-modulated irradiation of silicon samples and excess carrier density reveal a striking analogy to the above findings: the phase shift is greater than the actual effective carrier lifetime in the case of a positive derivative of lifetime with respect to excess carrier density, and vice versa. This work attempts to rearrange the mentioned previous findings in a quantitative theoretical description of light-biased dynamic measurements of effective carrier lifetime. Both light-biased differential lifetime measurements as well as harmonically time-modulated methods without additional bias light are shown to represent a limiting case in a general treatment of light-biased dynamic lifetime measurements derived here. Finally, we sketch a way to obtain actual recombination properties from differential measurements—referred to as a differential-to-actual (d2a) lifetime analysis, which does not require integration over the entire injection range.

• Microsecond carrier lifetime measurements in silicon via quasi‐steady‐state photoluminescence

  2011

  Progress in Photovoltaics Research and Applications · 25 Zitationen · DOI

  ABSTRACT Modulated quasi‐steady‐state photoluminescence is used in photovoltaics in order to measure the injection‐dependent effective minority carrier lifetime of silicon wafers. In spite of the very advantageous properties of this measurement technique, its wide dissemination in photovoltaics has been hampered so far because of a relatively poor sensitivity limit in terms of carrier lifetime. A systematic analysis of the sensitivity‐limiting mechanisms led to a substantial upgrade of sensitivity, tackling the range of effective lifetimes of 1 µs. This paper discusses the requirements to reach this level of sensitivity. Most prominently, the dependence of a silicon photodiode's response time with respect to the wavelength of the detected light is addressed. As an alternative, InGaAs photodiodes are implemented. The sensitivity of this method with respect to carrier lifetime is evaluated. Copyright © 2011 John Wiley & Sons, Ltd.
