Abstract

Antimony sulfide ( Sb 2 S 3) films on indium-doped tin oxide (ITO) glass substrates are easily synthesized by a solvothermal method from Sb ultrathin films and S powder as antimony and sulfur source, respectively. The crystalline Sb 2 S 3 films were characterized using X-ray powder diffraction (XRD) and Raman spectroscopy. The Sb 2 S 3 films are composed of micro-flakes of Sb 2 S 3. The composite of Sb 2 S 3 film and ITO substrate were used to fabricate the solar cell device ( ITO / Sb 2 S 3: P 3 HT / Au ), and I–V measurement of the device was performed. Under the optimized condition, the solar conversion efficiency is 0.0026% at 1 sun illumination.
