在这里，我们报告了高性能的小分子受体（SMA）为基础的有机太阳能电池（OSC）的组合，使二氟苯并噻二唑供体聚合物命名为PffBT 4 T-2DT和SMA命名为SF-PDI 2。发现SF-PDI 2与PffBT 4 T-2DT和非富勒烯OSC匹配得特别好，具有令人印象深刻的0.98 V的V-OC，并且实现了6.3%的高功率转换效率。我们的研究表明，PffBT 4 T-2DT是SMA基OSC的一种有前途的供体材料，选择匹配的SMA对于实现最佳OSC性能也很重要。
Here we report high-performance small molecule acceptor (SMA)-based organic solar cells (OSCs) enabled by the combination of a difluorobenzothiadiazole donor polymer named PffBT4T-2DT and a SMA named SF-PDI2. It is found that SF-PDI2 matches particularly well with PffBT4T-2DT and non-fullerene OSCs with an impressive V-OC of 0.98 V, and a high power conversion efficiency of 6.3% is achieved. Our study shows that PffBT4T-2DT is a promising donor material for SMA-based OSCs, and the selection of a matching SMA is also important to achieve the best OSC performance.
