Two-Dimensional Materials for Highly Efficient and Stable Perovskite Solar Cells

Abstract

Highlights Recent progress on the applications of 2D materials in perovskite solar cells is discussed from the views of bottom interfaces, top interfaces, and electrodes. The roles of van der Waals heterojunction in enhancing the performance of perovskite solar cells are highlighted. The future directions and challenges in development of 2D materials-based perovskite solar cells are provided.
