Using an environmentally friendly solvent, N‐methyl‐2‐pyrrolidone, a polymer with benzodithiophene (BDT) and thieno[3,4‐b]thiophene (TT) monomers and triethylene glycol monoether (TEG) side chains, PBDTTT‐TEG, can be processed into an active layer for a polymer solar cell (PSC). Combined with phenyl‐C 71‐butyric acid methyl ester (PC 71 BM) as the acceptor, the resulting PSC has a power conversion
使用环境友好的溶剂,ñ -甲基-2-吡咯烷酮,由苯并(BDT)聚合物和噻吩并[3,4-b]噻吩(TT)单体和三甘醇单醚(TEG)侧链,PBDTTT-TEG,罐将其加工成用于聚合物太阳能电池(PSC)的活性层。与苯基-C 71-丁酸甲酯(PC 71 BM)结合使用,所得PSC的功率转换效率(PCE)为5.23%。这是由非芳香族和非氯化溶剂制成的高效聚合物太阳能电池的第一个示例。
