Binary‐Metal Perovskites Toward High‐Performance Planar‐Heterojunction Hybrid Solar Cells. (14th August 2014) - Zuo, Fan
Abstract A simple, low temperature solution process for Pb/Sn binary‐metal perovskite planar‐heterojunction solar cells is demonstrated. Sn inclusion substantially influences the band‐gap, crystallization kinetics, and thin‐film formation leading to a broadened light absorption and enhanced film coverage on ITO/PEDOT:PSS. As a result, the optimized device shows a PCE exceeding 10%, which is the best result for binary‐metal perovskite solar cells so far.
