Recent progress in device engineering for semitransparent organic photovoltaics
摘要
Semitransparent organic photovoltaics (ST-OPVs), as a novel green energy acquisition technology, are one of the most promising applications in organic photovoltaics. Because of its intrinsic transmittance originated from adjustable absorption, light weight and flexibility, ST-OPVs, compared with other inorganic photovoltaics, show unique potential in wearable devices, self-powered greenhouse roofs and building integrated photovoltaics. To further promote the practicality and industrialization of ST-OPVs, the light utilization efficiency is still the focus of research. Hence, the recent progress of ST-OPVs is reviewed from the theoretical models, transparent top electrodes, the optical modification and selection of active layer materials. We hope that this paper will provide valuable guidelines for the ST-OPV research.
