Applications of Two-dimensional Materials in Perovskite Solar Cells

Abstract

As a new type of solar cell, perovskite solar cells (PSCs) exhibit significant potential due to the high performance. In recent years, they have garnered substantial attention due to their impressive photovoltaic conversion efficiency, low production costs, malleability, and other advantageous characteristics. However, there remains considerable room for the improvement in the performance of perovskite solar cells. Key factors that critically influence their performance include the charge transport layer, electrode materials, and overall cell structure. Two-dimensional (2D) materials, as emerging substances, facilitate the modifications of PSCs and enhance the electronic conduction. In this paper, a concise overview of perovskite solar cells is provided, followed by a summary of the current progress in enhancing their performance. The applications of 2D materials in the solar cell sector are highlighted. Finally, the existing challenges and issues confronting perovskite solar cells are discussed. This work will help promote the application of 2D materials in PSCs.
