Abstract

An efficient panchromatic planar perovskite solar cell is developed based on highly uniform, lead-reduced CH₃NH₃Sn_0.5Pb_0.5I₃ perovskite films with full film-coverage on the substrates. We demonstrate here that full-coverage of the CH₃NH₃Sn_0.5Pb_0.5I₃ films can be developed by a facile chlorobenzene-assisted spin-coating method. A power conversion efficiency of ~7 % is achieved using low-temperature processes, which is among the best-reported performance for panchromatic planar perovskite solar cells with a light-absorption over 1,000 nm.
