Recent advances of semitransparent organic solar cells

摘要

Semitransparent organic solar cells (STOSCs) are consisted of semitransparent active layer with a structure of both top and bottom transparent electrodes and can be used as power generation windows for both electricity generation and light transmission. In order to better realize these two functions, numerous attentions have been paid on the transparent top electrodes to acquire excellent transparency and maintain high conductivity, as well as the novel photoactive materials to achieve the absorption of near-infrared region. Herein, we review recent advances in a variety of transparent top electrodes and active materials for highly efficient STOSCs, moreover, we also further highlight the application of optical engineering in STOSCs, and give some thoughts about these STOSCs.
