S. NairLink: ECS Journal of Solid State Science and Technology, 8 (6) Q89-Q95 (2019) Abstract We present thin film antimony sulfide selenide prototype photovoltaic modules of area, seven cm2 and conversion efficiency (η) of 3.5%. The thin films of Sb2SxSe3-x (x, 0.8–1.6) of 120–180 nm in thickness were deposited on FTO/CdS(80 nm) substrates at 80°C from chemical bath containing potassium antimony tartrate, thioacetamide and sodium selenosulfate. Thin film of…

Special thanks for Dra Hailin Zao Hu at IER-UNAM who let me collaborate and learn from their group the methodology for TiO2 compact layer deposition. All the training was possible with the assistance of Ph.D. student Fabian and undergraduate Ing. Gabriela Abrego from UTEZ. Preparing TCO with magic tape for HRT layer deposition Spin coater and micropipette are the essential tools for TiO2 deposition First heating of the compact layer over a hot plate : low temperature Second and final heating - Sintering TiO2 on a muffle furnace : high temperature Compact TiO2 layer deposited over a TCO for thin-film…
