The Effect of Deposition Time Optimization on the Photovoltaic Performance of Sb2Se3 Thin-Film Solar Cells

Abstract

Antimony selenide (Sb2Se3) photovoltaic thin-film materials have been recognized as suitable thin-film photovoltaic candidates for sustainable development due to the low toxicity of their constituent elements and abundant reserves. In this study, we employed the close space sublimation (CSS) method to fabricate solar cells with the FTO/SnO2/Sb2Se3/P3HT/C device architecture. By optimizing the deposition time, we achieved (hk1) orientation-preferred Sb2Se3 films, the optimized device exhibited a peak efficiency of 5.06%. This work investigated the growth mechanism of antimony selenide using a complete characterization technique, while the experimental parameters were simulated and matched using Widget Provided Analysis of Microelectronic and Photonic Structures (wxAMPS) showing excellent potential in the deposition of optoelectronic thin films by close space sublimation.
