Recent Progress in Semitransparent Organic and Perovskite Solar Cells

Semitransparent organic and perovskite solar cells are considered promising photovoltaic (PV) devices that can be applied to power‐generating windows and facades of modern buildings and have achieved great progress in the past few years. Different from silicon‐based solar cells, the optical absorption of devices with organic and perovskite active layer materials can be easily tuned by modifying the chemical structure and adjusting the halide types or contents, respectively, to meet the demands of energy‐generating windows. In this review, the development progress of semitransparent PV (STPV) in terms of the selection of active layer materials, top transparent electrodes (TTEs), and strategies of enhancing the performance of STPVs is introduced. Meanwhile, the challenges and outlooks for the future development of STPVs are discussed.
