      Front Cover: Cu2ZnSnSe4 absorbers processed from solution deposited metal salt precursors under different selenization conditions (Phys. Status Solidi A 6/2012)

      Thin film solar cells based on low cost and earth-abundant or readily available elements, Cu2ZnSnSe4 or Cu2ZnSnSe4 (called kesterites according to their crystal structure), have received increasing interest during the last years since they have suitable physical properties for photovoltaics. A variety of vacuum and non-vacuum deposition methods have resulted in highest conversion efficiencies of about 10%. The metal ratios of the thin layers strongly influence the solar cell device efficiency. Therefore, it is very important to understand whether initial metal ratios are retained in the sulfurized/selenized layer or any losses occur due to the formation of volatile phases that originate during the precursor conversion. One reason for deviations in the metal composition is the thermal decomposition of kesterites at elevated temperatures in combination with low selenium vapor pressure. Fella et al. (pp. 1043–1048) report on controlling the overall composition of selenized Cu2ZnSnSe4 layers. A simple, sustainable, and low cost solution approach is employed for depositing the metal precursor. The cover image illustrates the precursor solutions and the secondary electron micrograph of a Cu2ZnSnSe4 absorber resulting in a highest conversion efficiency of 4.3%.

      Inside Back Cover: Sharp contrast of the density and size of Ga metal droplets on photolithographically patterned GaAs (100) by droplet epitaxy under an identical growth environment (Phys. Status Solidi A 6/2012)

      Ming-Yu Li, Jihoon Lee, Zhiming Wang, Yusuke Hirono, Jiang Wu, Sangmin Song, Sang-Mo Koo, Eun-Soo Kim and Gregory J. Salamo

      Article first published online: 12 JUN 2012 | DOI: 10.1002/pssa.201290013

      Due to the highly flexible nature of self-assembly and a wide range of applications in molecular beam epitaxy, droplet epitaxy is gaining significant research interest for the fabrication of low-dimensional semiconductor quantum- and nano-structures by self-assembly. Optoelectronic device applications such as solar cells using GaAs quantum rings, inter-sublevel infrared photodetectors and lasers have been demonstrated through droplet epitaxy. Thus, the control of density and size of metal droplets (MDs) on a patterned GaAs(100) surface becomes an essential step for further development. Ming-Yu Li et al. (pp. 1075–1079) present an attempt to demonstrate a sharp contrast in size and density of Ga MDs on patterned GaAs(100) through conventional photolithography. The etched surface exhibits a much higher density and smaller diameter and height of MDs. As clearly evidenced by SEM and AFM, the MD density between etched (patterned) and un-etched (un-patterned) surfaces can be sharply different up to one order of magnitude under identical growth conditions.

      Back Cover: Texture-etched ZnO as a versatile base for optical back reflectors with well-designed surface morphologies for application in thin film solar cells (Phys. Status Solidi A 6/2012)

      W. Böttler, V. Smirnov, J. Hüpkes and F. Finger

      Article first published online: 12 JUN 2012 | DOI: 10.1002/pssa.201290014

      Thumbnail image of graphical abstract

      The improvement of light trapping is of great importance in the development of high efficiency thin film silicon solar cells. Texture-etched ZnO has been often used as front contact in solar cells, where the requirements for the transmission and resistance limit the optimization of the texture morphology. The work by Böttler et al. (pp. 1144–1149) demonstrates that in the case of solar cells where the ZnO layer is used as a back reflector, its morphology can be tuned over a wide range by controlling etching time and as-deposited thickness of the ZnO layer. A statistical analysis of the ZnO surface morphology indicates that with optimized diameter, depth and opening angle of the craters on the surface one can improve light trapping and the conversion efficiency of solar cells.
