研究目的
This review discusses the important progress of perylene diimide (PDI)-based polymers as nonfullerene acceptors (NFAs) in all polymer solar cells (all-PSCs) since 2014.
研究成果
PDI-based polymers have shown promising results as nonfullerene acceptors in all-PSCs, with recent advancements leading to PCEs over 8%. Future research should focus on improving electron transport properties and exploring novel FPDI units to enhance photovoltaic performance.
研究不足
The review highlights the challenges in achieving high power conversion efficiencies (PCEs) with PDI-based polymers, including issues related to aggregation, phase separation, and the need for suitable donor-acceptor pairs.
