In this work, we study an alternative path for Sb2Se3 preparation by thermal evaporation for low temperature substrate deposition. Thermal evaporation delivered, up to now, lower efficiency devices compared to close space sublimation based solar cells. One of the drawbacks of thermal evaporation for Sb2Se3 is the re-evaporation of Se on the substrate, for this reason we present an alternative route to adjust the stoichiometry of selenium deficient Sb2Se3 films by adding an excess of selenium (Se) for the deposition of 800 nm thin film by co-evaporation of Se and Sb2Se3. Thin films were deposited on Glass/FTO/SnO2/CdS substrate and their structural and electrical properties have been studied, together with the analysis of the finished devices.

Abstract

In this work, we study an alternative path for Sb2Se3 preparation by thermal evaporation for low temperature substrate deposition. Thermal evaporation delivered, up to now, lower efficiency devices compared to close space sublimation based solar cells. One of the drawbacks of thermal evaporation for Sb2Se3 is the re-evaporation of Se on the substrate, for this reason we present an alternative route to adjust the stoichiometry of selenium deficient Sb2Se3 films by adding an excess of selenium (Se) for the deposition of 800 nm thin film by co-evaporation of Se and Sb2Se3. Thin films were deposited on Glass/FTO/SnO2/CdS substrate and their structural and electrical properties have been studied, together with the analysis of the finished devices.
