Perovskite solar cells (PSCs) have rapidly advanced and achieved performance comparable to silicon solar cells. Semi-transparent PSCs (ST-PSCs) are a promising application that utilizes the tunable transmittance of perovskite photoactive layers. To overcome challenges, studies are focusing on band-gap tuning, high-performance charge transport layers, electrodes, and creating island-shaped microstructures. This review provides a summary of innovative approaches in ST-PSCs, including advancements in perovskite photoactive layers, transparent electrodes, device structures, and their applications in tandem solar cells (TSC) and building-integrated photovoltaics (BIPV).
Perovskite solar cells (PSCs) are advancing rapidly and have reached a performance comparable to that of silicon solar cells. Recently, they have been expanding into a variety of applications based on the excellent photoelectric properties of perovskite. Semi-transparent PSCs (ST-PSCs) are one promising application that utilizes the tunable transmittance of perovskite photoactive layers, which can be used in tandem solar cells (TSC) and building-integrated photovoltaics (BIPV). However, the inverse relationship between light transmittance and efficiency is a challenge in the development of ST-PSCs. To overcome these challenges, numerous studies are underway, including those on band-gap tuning, high-performance charge transport layers and electrodes, and creating island-shaped microstructures. This review provides a general and concise summary of the innovative approaches in ST-PSCs, including advances in the perovskite photoactive layer, transparent electrodes, device structures and their applications in TSC and BIPV. Furthermore, the essential requirements and challenges to be addressed to realize ST-PSCs are discussed, and the prospects of ST-PSCs are presented.
