Abstract
Thin films based on the ternary complex oxide Bi0.50Fe0.4WOq with a cubic pyrochlore structure were obtained and used for the first time as electron-transport layers in perovskite solar cells. The measured power conversion efficiency was ∼ 4 rel% higher than that of state-of-the-art TiO2-based perovskite solar cells.
