SOLAR cellsSEMICONDUCTORSPOLYMERSHETEROJUNCTIONSLIGHT absorptionNaphthalenediimide-based n-type polymeric semiconductors are extensively used for constructing high-performance all-polymer solar cells (all-PSCs). For such all-polymer systems, charge recombination can be reduced by using thinner active layers, ...
Four polymers based on perylenediimide co-polymerized with thiophene, bithiophene, selenophone and thieno[3,2-b]thiophene were investigated as the acceptor materials in all-polymer solar cells. Two different donor polymers, poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b′]di...

Polymerized small-molecule acceptors (PSMAs) based on nonfused-core structures have obtained much attention in the domain of all-polymer solar cells (all-PSCs) due to simplified synthetic complexity. In this work, two nonfused PSMAs, namely, P1 and P2, with similar molecular backbones but ...
The non-fully conjugated polymer as a new class of acceptor materials has shown some advantages over its small molecular counterpart when used in photoactive layers for all-polymer solar cells (all-PSCs), despite a low power conversion efficiency (PCE) caused by its narrow absorption spectra. He...
