Abstract
In this work, we investigated the effect of Europium (Eu) doping of zinc oxide on the performance of inverted organic solar cell. ZnO and Eu-doped ZnO thin films have been prepared by sol-gel spin coating technique. Inverted polymer solar cells containing Eu-doped ZnO as an electron transport layer with device structure ITO/Eu-doped ZnO/PTB7: PC70BM/MoO3/Al have been fabricated. The device performance has been optimized by varying the Europium doping concentration. The inverted organic solar cell with 5.96% Eu-doped ZnO shows the highest power conversion efficiency of 7.03% which means significant improvement in power conversion efficiency can be obtained by incorporating Eu into the ZnO films.
