A. Jasenek,Uwe Rau,T. Hahn,G. Hanna,Markus A. Schmidt,M. Hartmann,H.W. Schock,Jürgen H. Werner,B. Schattat,S. Kraft,K.-H. Schmid,Wolfgang Bolse +11 more
TL;DR: In this paper, the degradation of ZnO/CdS/Cu(In,Ga)Se2 heterojunction solar cells for space applications and the defect generation in polycrystalline Cu(In-Ga)-Se2 thin films by irradiation with 1-MeV electrons with fluences up to φe=5×1018 cm-2.
Journal ArticleDOI

Stefan Stefanov,J.C. Conde,A. Benedetti,C. Serra,Jürgen H. Werner,Michael Oehme,Jörg Schulze,Dan Buca,Bernhard Holländer,S. Mantl,Stefano Chiussi +10 more
TL;DR: In this article, the synthesis of heteroepitaxial germanium tin (GeSn) alloys using excimer laser processing of a thin 4'nm Sn layer on Ge has been demonstrated and studied.
Journal ArticleDOI
Room Temperature Direct Band Gap Emission from Ge p-i-n Heterojunction Photodiodes
TL;DR: In this article, a Si-substrate-based Ge p-i-n heterojunction photodiode structure operated under forward bias was observed for room temperature direct band gap emission.
Journal ArticleDOI
Highly resistive Cu(In, Ga)Se2 absorbers for improved low-irradiance performance of thin-film solar cells
TL;DR: In this paper, the authors investigated the suitability of thin-film solar cells for application under low irradiance conditions with irradiance E 10 kΩ cm2 of the solar cells and found that the shunt resistance of these solar cells originates from highly localised shunt regions in the absorber material.
Proceedings ArticleDOI
Outdoor efficiency of different photovoltaic systems installed in Cyprus and Germany
TL;DR: In this paper, the outdoor efficiencies of thirteen different types of photovoltaic (PV) modules have been evaluated by using direct outdoor measurements and data analysis on the measured metereological and operational data collected by the installed sensors present at the two test sites.
