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

Deposition of nanocrystalline Sb(2)S(3) onto a mesoporous TiO(2) photoanode is an important process in the fabrication of Sb(2)S(3)-sensitized solar cells. In order to generate oxide-free nanosized Sb(2)S(3), a single-source precursor for the chemical bath deposition of Sb(2)S(3) in nonaqueous media, Sb(III)(thioacetamide)(2)Cl(3), was synthesized and used to produce high-quality Sb(2)S(3) for solar cells.
