Abstract

Perovskite solar cells (PSCs) are a novel type of photovoltaic cells, whose basic structure is composed of perovskite-type compounds. The energy band structure of perovskite materials endows them with excellent light absorption capability and high carrier mobility, enabling efficient conversion of solar energy into electricity. In recent years, the power conversion efficiency (PCE) of PSCs has increased rapidly, with the certified laboratory efficiency reaching up to 26.9%. This paper summarizes various application methods of graphene-based materials as additives in electron transport layers (ETLs) of PSCs, and analyzes the future application potential in this field. Compared with conventional silicon-based solar cells, PSCs feature lower production cost, lighter weight, and broader material selectivity.
