Bismuth iron tungstate pyrochlore thin films for photovoltaic applications

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 similar to 4 rel% higher than that of state-of-the-art TiO2-based perovskite solar cells.

Automated summary

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