研究目的
To develop scalable fabrication methods for semitransparent organic photovoltaic modules based on non-fullerene acceptors, aiming for integration into architectonic elements like windows with high transparency and efficiency.
研究成果
The work demonstrates the feasibility of fabricating semitransparent OPV modules with high transparency and efficiency using scalable techniques. The use of non-fullerene acceptors with strong NIR absorption is highlighted as key for meeting industrial requirements for BIPV applications.
研究不足
The study is limited by the trade-off between transparency and efficiency, the conductivity of semitransparent electrodes, and the scalability of the fabrication process to larger areas.
