| abstract |
A composition used to form the active layer of a solar cell or hydrogen fuel cell that comprises, consists of or consists essentially of a homogenous dispersion, poly(3-hexylthiophene-2,5-diyl) (P3HT) and 1-(3-methoxycarbonyl)propyl-1-phenyl[6,6]C 61 (PCBM). The homogenous dispersion comprises, consists of or consists essentially of graphene oxide (GO) or reduced graphene oxide (RGO) and sulfonated polystyrene (PSS) or para-methoxy-N-methylamphetamine (PMMA). The GO or RGO can be functionalized with a metal, preferably gold (Au), platinum (Pt), palladium (Pd) or ferric oxide (Fe 2 O 3 ). |
