摘要

A non-fullerene acceptor, SCPDT-PDI4, composed of perylenediimide (PDI) and a spiro core of 4,4’-spirobi[cyclopenta[2,1-b;3,4-b’]dithiophene] (SCPDT), has been developed. SCPDT-PDI4 exhibits a unique 3D structure and isotropic charge transport properties. Organic solar cells based on SCPDT-PDI4 and a donor polymer of poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b’]di-thiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2–6-diyl)] PTB7-Th achieved a remarkable quantum efficiency of 7.11%, indicating SCPDT-PDI4 is a very promising non-fullerene acceptor for organic solar cells
