Abstract:

Semitransparent organic photovoltaics(ST-OPVs) have intrinsic advantages over other inorganic photovoltaics due to the tunable electronic energy levels and selective absorption spectra of the active layer material in applications such as power-generating roofs for greenhouses and color-adjustable windows for modern buildings and exterior walls. With the rapid development of highly efficient narrow bandgap polymer donors and near-infrared non-fullerene acceptor materials, ST-OPVs have made rapid advances in light utilization efficiency over the past decade.The intrinsic and optically modified semitransparent devices exceed 3% and 5%, respectively. In order to further promote the practical use of semitransparent organic photovoltaic, how to further improve the optical efficiency of the device is still the key research direction. Therefore, this paper reviews the recent important progress of ST-OPVs from the theoretical model of the semitransparent device, the design of the active layer material and the optical modification of the device, so as to provide a reference for the improvement of the device performance in the future.

Key words: Semitransparent organic solar cell, Active layer material, Optical modification of device
