Recent Progress of Layered Perovskite Solar Cells Incorporating Aromatic Spacers

Abstract

Highlights Layered two-dimensional (2D) perovskites are emerging photovoltaic materials with superior structural and environmental stability. Aromatic spacers offer unique advantages over aliphatic spacers, including higher dielectric constants, better charge transport properties, and the ability to regulate crystal arrangement, making them indispensable for constructing efficient and stable 2D perovskites. This review mainly focus on recent progress and achievements in developing aromatic spacer-based 2D perovskite solar cells.
