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

Nanocrystalline Sb 2 S 3 was synthesized using chemical bath deposition, and TiO 2 –Sb 2 S 3 composite electrodes were fabricated by combining the nanocrystalline Sb 2 S 3 with mesoporous TiO 2 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.
