Graded energy band engineering for efficient perovskite solar cells
Abstract: Metal‐halide perovskite materials have attracted extensive attention in the field of photovoltaics due to their excellent optical and electrical properties. In just several years, the power conversion efficiency (PCE) of metal‐halide perovskite solar cells quickly increased from 3.8% to 25.2%. To further realize their theoretical PCE limit and improve their stability, matched energy levels at the interfaces among the perovskite device are critical. Appropriate energy‐level tailoring facilitates charge separation and transport, which contribute to increased open‐circuit voltage, short‐circuit current, and fill factor. In band engineering, the construction of the graded band structure can match the interfacial energy levels on both sides at the same time and provide a stronger build‐in electric field for carrier transfer. Herein, this review focuses on the graded band structure design, summarizes the recent application progress of the graded band structure in PSCs, and discusses possible promising research directions for further improvements.
