摘要
Highly crystalized perovskite film with smooth surface is of great importance to obtain high photovoltaic performances. In this work, UV irradiation is applied to the perovskite films during their thermal annealing process. It is revealed that UV irradiation treatment can largely improve the perovskite crystallization and reduce defects. This greatly improves power conversion efficiency (PCE) and environmental stability of the resulted solar cells (ITO/SnO2/perovskite/Spiro-OMeTAD/Au). By combining CH3O-PEAI surface passavation, an outstanding PCE of 23.24% is achieved. This article is protected by copyright. All rights reserved.
