Enhancing perovskite solar cell efficiency and stability through the incorporation of BDAI2 and DMPDAI2

Abstract

This research explores the incorporation of 2D materials, BDAI₂ and DMPDAI₂, into perovskite solar cells, demonstrating enhanced efficiency and stability in the resulting devices. These materials facilitate the formation of quasi-2D perovskite layers, leading to denser films and smaller grain sizes. Through extensive analyses, including XRD, XPS, and UPS, this study highlights the structural and electronic modifications induced by these 2D materials, resulting in improved conductivity and carrier mobility. Additionally, Sentaurus TCAD simulations validate the observed increase in power conversion efficiency (PCE), supporting the experimental findings. Integrating BDAI₂ and DMPDAI₂ presents a promising approach for optimizing perovskite solar cells’ performance and reliability.
