Bi2S3 is a promising material for Quantum Dot sensitized solar cells (QDSSCs). Probably the major reasons are: its low toxicity, low cost and its high absorption coefficient. The band gap of bulk Bi2S3 material is 1.3eV but in Quantum Dots(QDs) it varies from 1.3 to 1.7eV. In present work, we are reporting Bi2S3 QDs Sensitized over mesoporous oxide (TiO2) and application of copper Nanoparticles (NPs) fabrication on TiO2/Bi2S3 devices. The deposition of Bi2S3 QDs on TiO2 was done by Successive Ionic Layer Adsorption and Reaction (SILAR) and fabrication of Cu NPs on TiO2/Bi2S3 by electrophoretic deposition method. Finally, the maximum power conversion efficiency (PCE) is 3.90 % for TiO2/Bi2S3/Cu with functionalized multi walled carbon nanotubes (MWCNTs) as a counter electrode.
