Sb2Se3 is introduced as the absorber layer for thin film photovoltaics because of its very attractive material, optical, and electrical properties. High quality Sb2Se3 films are produced using a hydrazine solution process, and a heterojunction TiO2/Sb2Se3 solar cell achieving 2.26% efficiency with an impressive high open circuit voltage of 0.52 V is reported.
