Sb2S3 has been widely used as a successful light sensitizer for efficient inorganic organic heterojunction solar cells due to its low optical absorption onset and its high absorption coefficient in the visible.Here,the photovoltaic performance of Sb2S3-sensitized heterojunction photoanodes,which were fabricated by a simple deposition of Sb2S3 on TiO2 mesoporous thin films by low temperature chemical bath method and then annealed under Argon atmosphere,is reported.
