A PTB7-based cationic narrow band-gap polyelectrolyte, named PTB7-NBr, has been designed and synthesized as a cathode interfacial material for polymer solar cells. PTB7-NBr exhibits excellent cathode interfacial modification in solar cells with PTB7 and PTB7-Th as donor polymer and a high PCE of 9.24% was achieved.
一种基于PTB7的阳离子窄带隙聚电解质,命名为PTB7-NBr,已被设计并合成作为聚合物太阳能电池的阴极界面材料。在以PTB7和PTB7-Th作为给体聚合物的太阳能电池中,PTB7-NBr表现出优异的阴极界面修饰性能,实现了9.24%的高光电转换效率。
