摘要

We demonstrate that solution processed graphene oxide (GO) grafted polyethylenimine ethoxylate (PEIE) is an efficient electron transport layer for organic solar cells with an active layer that consists of poly({4,8-bis [(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl}{3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno-[3,4-b]thiophenediyl}) (PTB7) mixed with [6,6]-phenyl C-71 butyric acid methyl ester (PC71BM). The optimized GO: PEIE demonstrated the best efficiency of 8.21% compared to that of the GO and PEIE devices.
