Abstract

Nanocrystalline Cd-doped TiO₂ thin films have been prepared by sol-gel method. X-ray diffraction analysis reveals that TiO₂ and Cd-doped TiO₂ nanocrystalline thin films are of anatase phase. The average grain size of TiO₂ and Cd-doped TiO₂ nanocrystalline thin films was found to lie in the range of 15-18 nm. Solar cells have been fabricated with a device structure of ITO/Cd-doped TiO ₂/P3HT:PC₇₁BM/MoO₃/Al configuration. The power conversion efficiency of the inverted organic solar cell with Cd-doped TiO ₂ is 3.06% and is higher than that of TiO₂ based organic solar cell (2.64%).
