Ionic Liquid Assisted Imprint for Efficient and Stable Quasi-2D Perovskite Solar Cells with Controlled Phase Distribution
Abstract
Highlights The strategy of imprint assisted with methylamine acetate effectively ameliorates the morphology of the film, optimize the internal phase distribution, and enhance the charge transfer of the perovskite film. The combination of imprinting with additive engineering improves the phase distribution within quasi-2D perovskite and promote the carrier transport, resulting in a power conversion efficiency of 18.96% with specific good reproducibility.
