All‐Polymer Solar Cells Based on Absorption‐Complementary Polymer Donor and Acceptor with High Power Conversion Efficiency of 8.27%

High-efficiency all-polymer solar cells with less thickness-dependent behavior are demonstrated by using a low bandgap n-type conjugated polymer N2200 as acceptor and an absorption-complementary difluorobenzotriazole-based medium-bandgap polymer J51 as donor.
