Sb2S3 solar cells: functional layer preparation and device performance

Abstract

Photovoltaic power generation, as a rapidly growing new energy source, is a technology that uses a semiconductor to convert light energy into electrical energy. Sb₂S₃ solar cells possess the advantages of simple binary components, abundant resources, nontoxicity, and excellent stability; they have recently attracted extensive investigation interest. Various strategies, such as solution and vacuum deposition, have been used to fabricate functional layers, including Sb₂S₃ photoactive layers, electron transport layers and hole transport layers. Here, we briefly review the preparation methodologies, morphologies, structures, optoelectronic properties and the corresponding solar cell performance of functional layers for both planar heterojunction solar cells and mesoporous sensitized solar cells. Some viewpoints of further improvement of Sb₂S₃ solar cell conversion efficiency from the aspect of material fabrication and modification are given.
