Abstract
Antimony selenide(Sb2Se3) is a promising absorber material for thin film photovoltaics becauseof its attractive material, optical and electrical properties. In recent years,the power conversion efficiency (PCE) of Sb2Se3 thin film solar cells hasgradually enhanced to 5.6%. In this article, we systematically studied thebasic physical properties of Sb2Se3 such as dielectric constant, anisotropicmobility, carrier lifetime, diffusion length, defect depth, defect density andoptical band tailstates. We believe such a comprehensive characterization of the basic physicalproperties of Sb2Se3 lays a solid foundation for further optimization ofsolar device performance.
