Large formamidinium lead trihalide perovskite solar cells using chemical vapor deposition with high reproducibility and tunable chlorine concentrations

Matthew R. Leyden, Michael V. Lee, Sonia R. Raga, Yabing Qi

Abstract

Formamidinium perovskite films have been prepared by chemical vapor deposition, with cells demonstrating PCEs up to 14.2%, stability up to 155 days, semitransparency, large-area (1 cm 2 ), and tunable chlorine concentrations.
