Nanocrystalline Sb2S3 sensitized TiO2 photoanode preparation and its application in solar cells

Abstract

Nanocrystalline Sb2S3 was synthesized using chemical bath deposition, and TiO2–Sb2S3 composite electrodes were fabricated by combining the nanocrystalline Sb2S3 with mesoporous TiO2 thin films. The composite electrodes were characterized by XRD, SEM, TEM, EDX, and UV–Visible absorption. P3HT and CuSCN were used as hole-transporting materials, and thermally evaporated silver films were used as counter electrodes in the fabricated solar cells. The solar cells with P3HT or CuSCN as hole-transporting material exhibit the highest efficiencies of 0.34 and 0.47 %, respectively.
