Small molecule BODIPY dyes incorporating conjugated substituents at the β sites have been synthesized. Solution processed inverted bulk heterojunction cells were fabricated from the blends of the dyes and PC71BM. The cells exhibited very high open-circuit voltages (>0.9 V) and a high conversion efficiency of 3.22% has been achieved.
我们合成了在δ位点加入共轭取代基的小分子 BODIPY
染料。利用这些
染料和 PC71BM 的混合物制造出了溶液处理的倒装体异质结电池。这种电池的开路电压非常高(大于 0.9 V),转换效率高达 3.22%。
