Buried Interface Modification in Perovskite Solar Cells: A Materials Perspective

Organic–inorganic hybrid perovskite solar cells (PSCs) are promising third-generation cells. They exhibit high power conversion efficiency (PCE) and, in theory, can be manufactured with less energy than several more established photovoltaic technologies, particularly solution-processed PSCs. Various materials have been widely utilized to modify the buried bottom interface improve performance and long-term stability of Here, latest progress modifying enhance PSCs is examined from a standpoint, which classified into inorganic salts, organic molecular polymer, carbon materials, perovskite-related 2D materials. This material perspective useful determining tactics for achieving theoretical PCE value It also serves as solid reference adjustment other layered structure heterojunction devices.
