Abstract :
A solution-processed vanadium oxide interlayer is introduced between the organic layer and the electrode for improving the performance of the polymer/ZnO nanorod hybrid solar cells. The results indicate that the vanadium oxide interlayer can serve as an electron-blocking layer to suppress the leakage current and an optical spacer to increase light absorption. As a result, the power conversion efficiency is improved from 2.52% to 3.56%, with a fill factor of 60% under 100 mW/cm2 irradiation.
