Synthesis of Sb2S3 films on conducting substrate and its application in hybrid solar cell devices

Antimony sulfide (Sb2S3) 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 Sb2S3 films were characterized using X-ray powder diffraction (XRD) and Raman spectroscopy. The Sb2S3 films are composed of micro-flakes of Sb2S3. The composite of Sb2S3 film and ITO substrate were used to fabricate the solar cell device (ITO/Sb2S3: P3HT/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.
