Lead acetate precursor based p-i-n perovskite solar cells with enhanced reproducibility and low hysteresis

Abstract

A low temperature approach for the fabrication of p-i-n perovskite solar cells is presented. Using lead acetate-based precursors, flat and homogeneous CH₃NH₃PbI₃ films, compatible with the use of thin organic charge transport layers, can be obtained. The corresponding solar cells showed power conversion efficiency up to 12.5%, with remarkable reproducibility and very low hysteresis.
