Enhanced Environmental Stability of Planar Heterojunction Perovskite Solar Cells Based on Blade‐Coating. Issue 4 (18th October 2014) - Kim, Jong H.
Abstract A simple and effective method to prepare air‐processable perovskite films is developed. The blade‐coated perovskite films feature self‐assembled air‐protection patches, and solar cells based on these film showed significantly improved air‐stability with high power conversion efficiencies up to 9.52%. It is also demonstrated that the blade‐coating process is applicable to the fabrication of high efficiency (12.21%) perovskite solar cells.
