摘要：

A comparison study of photovoltaic properties of an oligomer and a polymer based on the same backbone structure is conducted to show that high-efficiency small molecules can be developed from breaking down polymers. The oligomer attains high-efficiency as a result of the high-degree molecular ordering and the excellent intrinsic phase separation with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM). © 2015 WILEY-VCH Verlag GmbH & Co.
