Branched‐alkyl‐substituted poly(thieno[3,4‐c]pyrrole‐4,6‐dione‐alt‐3,4‐difluorothiophene) (PTPD[2F]T) can be used as a polymer acceptor in bulk heterojunction (BHJ) solar cells with a low‐band‐gap polymer donor (PCE10) commonly used with fullerenes. The “all‐polymer” BHJ devices made with PTPD[2F]T achieve efficiencies of up to 4.4 %. While, to date, most efficient polymer acceptors are based on perylenediimide
支链烷基取代的聚(噻吩并[3,4- c ^ ]吡咯-4,6- dione- ALT -3,4- difluorothiophene)(PTP-D [2F] T)可以用作在本体异质结的聚合物受体(BHJ )具有低带隙聚合物供体(PCE10)的太阳能电池,通常与富勒烯一起使用。用PTPD [2F] T制造的“全聚合物” BHJ设备的效率高达4.4%。尽管迄今为止,最有效的聚合物受体是基于per二酰亚胺或萘二酰亚胺基序的,但我们对PTPD [2F] T聚合物的研究表明,具有充分取代的主链的线性全噻吩体系也可能有益于具有聚合物的高效BHJ太阳电池捐助者。
