Abstract

A nonfullerene polymer solar cell with a high efficiency of 9.26% is realized by using benzodithiophene-alt-fluorobenzotriazole copolymer J51 as a medium-bandgap polymer donor and the low-bandgap organic semiconductor ITIC with high extinction coefficients as the acceptor.

Keywords: ITIC; extinction coefficients; fluorinated conjugated polymer donors; nonfullerene polymer solar cells.
