Abstract

Compounds made up of metalloid/metallic cations and chalcogen anions like SnS, GeSe, and Sb2Se3 have made a nonnegotiable impact in new and emerging absorbers for thin film photovoltaic materials. Some of the chalcogenide-based solar cells performed way better than other types of thin-film solar cells. Sb2Se3 based solar cells are one such material. Their day-by-day enhanced performance and stability have scaled up the research focus on this material. These have achieved an efficiency of 9.2% which is becoming comparable to c-Si cell-based solar cells and 22.9% of CIGS thin film chalcanogides-based solar cells (Lee and Lo, 2009). Apart from stoichiometric studies, low cost, high throughput, process tolerance, and efficiency are the main features of this technology for industrial applications. Herein, we have reviewed parameters like factors affecting the device, challenges, solutions, and prospects of Sb2Se3 based solar cells. We have extensively discussed the possible techniques to improve the existing Power conversion efficiency of the solar cell.
