Highly compact and uniform CH3NH3Sn0.5Pb0.5I3 films for efficient panchromatic planar perovskite solar cells

An efficient panchromatic planar perovskite solar cell is developed based on highly uniform,lead-reduced CH3NH3Sn0.5Pb0.5I3 perovskite films with full film-coverage on the substrates.We demonstrate here that full-coverage of the CH3NH3Sn0.5Pb0.5I3 films can be developed by a facile chlorobenzene-ass...

Description
Summary:An efficient panchromatic planar perovskite solar cell is developed based on highly uniform,lead-reduced CH3NH3Sn0.5Pb0.5I3 perovskite films with full film-coverage on the substrates.We demonstrate here that full-coverage of the CH3NH3Sn0.5Pb0.5I3 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.
