Titanium dioxide (TiO2) nanofibers (NF) including graphene oxide (GO) and silver (Ag) nanoparticles (NPs) were preparedusing the sol-gel method and electrospin technique. The photovoltaic conversion efficiency (η) of the modified dye-sensitizedsolar cell (DSSC) with TiO2/GO/Ag nanofibers on the photoelectrode was measured under various low light intensities. Theincorporation of GO and Ag nanoparticles led to rapid electron transport and a reduced incidence of electron recombination. Thesynthesized TiO2/GO/Ag nanofibers had a large specific surface area and high porosity that promoted dye absorption at thephotoanode. Theηof the TGAP modified photoelectrode was 34% higher than that of a standard DSSC photoelectrode. Thisstudy showed that the highestηfor the TGAP modified photoelectrode was 6.56% which occurred at 30 mW/cm2, this wasattributed to the decreased electron recombination under those low light conditions.
