A chemical precursor for depositing Sb2S3 onto mesoporous TiO2 layers in nonaqueous media and its application to solar cells

Abstract

Deposition of nanocrystalline Sb₂S₃ onto a mesoporous TiO₂ photoanode is an important process in the fabrication of Sb₂S₃-sensitized solar cells. In order to generate oxide-free nanosized Sb₂S₃, a single-source precursor for the chemical bath deposition of Sb₂S₃ in nonaqueous media, Sb(III)(thioacetamide)₂Cl₃, was synthesized and used to produce high-quality Sb₂S₃ for solar cells.
