Characterization of Cu(In,Ga)(Te,S)(2) thin films grown on stainless steel foil substratesIo
Karaca, Abdullah; Başol, Bülent M.; Olgar, Mehmet Ali; Büyüklimanlı, Temel; Tomakin, Murat; Küçükömeroğlu, Tayfur; Bacaksız, Emin (IOP Publishing, 2023)In this study, Cu(In,Ga)(Te,S)(2) (CIGTS) thin films with [Ga]/([In] +/- [Ga]) atomic ratios in the ranges of 0.22-0.28 and 0.50-0.67 were fabricated using a two-stage technique. During the first stage of the technique, ... -
Deposition of CdSeTe alloys using CdTe-CdSe mixed powder source material in a close-space sublimation process
Çiriş, Ali; Başol, Bülent M.; Atasoy, Yavuz; Karaca, Abdullah; Küçükömeroğlu, Tayfur; Tomakin, Murat; Bacaksız, Emin (Springer, 2021)CdSexTe1-x films were deposited using a close-space sublimation (CSS) method and CdSe + CdTe mixed powders as the source material. Composition of the source was changed to obtain films with varying x values, and the resulting ... -
Effect of CdS and CdSe pre-treatment on interdiffusion with CdTe in CdS/CdTe and CdSe/CdTe heterostructures
Çiriş, Ali; Başol, Bülent M.; Atasoy, Yavuz; Küçükömeroğlu, Tayfur; Karaca, Abdullah; Tomakin, Murat; Bacaksız, Emin (Elsevier, 2021)High efficiency CdTe solar cell structure has the configuration of CdS/CdSe/CdTe. Depending on the deposition and post deposition techniques employed, this stack is often subjected to high temperatures, often in presence ... -
