摘要：
The nanorod/nanowire arrays of narrow-bandgap semiconductors are a kind of great potential light-harvesting material for photovoltaic devices due to their excellent optoelectrical properties. Here, a gamma-butyrolactone (GBL) solution-processed inorganic Sb2S3 nanorods on the TiO2 film is developed to fabricate light-harvesting layer for efficient inorganic Sb2S3/TiO2 semiconductor heterojunction thin film solar cells. The morphology, absorption properties, crystallinity and grain orientation of the Sb2S3 nanorods heterojunction film is investigated by scanning electron microscopy (SEM), ultraviolet-visible spectroscopy (UV-vis), X-ray diffraction (XRD) techniques. The inorganic Sb2S3/TiO2 nanorods heterojunction thin film solar cells deliver a champion power conversion efficiency of 4.14%, which is a considerable efficiency for the solar cells based on GBL solution-processed inorganic Sb2S3 nanorods heterojunction thin film.
