Abstract

Nanocrystalline TiO2 and Sn-doped TiO2 thin films were prepared by sol–gel spin coating method. The crystallinity and anatase phase of TiO2 and Sn-doped TiO2 were confirmed from X-ray diffraction analysis. The EDAX analysis also confirmed the presence of tin, oxygen and titania elements. By fabricating an inverted organic solar cell with device configuration of ITO/Sn-doped TiO2/active layer/MoO3/Al, power conversion efficiency (PCE) of the Sn-doped TiO2 was observed to be 3.08% compared to the TiO2 based solar cell of 2.64%. Keywords: Doped TiO2, Polymer solar cells, Sol–gel method, XRD
