Abstract A novel solution-processed graphene-based nanomaterial was synthesized by treating graphene oxide (GO) with 2,5,7-trinitro-9-fluorenone-4-carboxylic acid (TNF) moieties, via simple synthetic procedures. The yielded GO-TNF was thoroughly characterized and it was shown that GO-TNF presents favorable highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels to function as a bridge structure between the polymer donor 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) and the fullerene derivative acceptor [6,6]-phenyl-C71 -butyric-acid-methylester (PC71 BM). In this context, GO-TNF was incorporated within the binary photoactive layer, in different ratios (1-3% ratio to the polymer), for the effectual ternary organic solar cells (OSCs) fabrication of the inverted structure ITO/PFN/PTB7:GO-TNF:PC71 BM/MoO3 /Al, entirely in inert atmosphere. The addition of 2% GO-TNF led to an overall device performance improvement, achieving a champion power conversion efficiency (PCE) of 8.71%, which was enhanced by ~10%, compared to the reference cell.
