Abstract: In this investigation, the electrospun reduced graphene oxide-titanium oxide composite nanofibers as an electron transporting materials have been employed for the perovskite solar cells. The synthesized electron transporting materials have been used for the fabrication of mixed-cation lead mixed-halide (FAPbI3)0.85(MAPbBr3)0.15 perovskite solar cells. The influence of reduced graphene oxide on titanium oxide nanofibers and their morphological and electronic properties have been investigated in detail. The optimized device having FTO/Bl-TiO2/rGO4–TiO2/(FAPbI3)0.85(MAPbBr3)0.15/spiro-MeOTAD/Au configuration exhibited a η = 17.66% power conversion efficiency with an open circuit voltage of 1.070 V, short circuit current density of 22.16 mAcm−2 and fill factor of 0.754. This obtained efficiency is much higher than that of mesoporous-titanium oxide (14.39%), pristine-titanium oxide nanofibers (15.82%) and other reduced graphene oxide-titanium oxide composite nanofibers based electron transporting materials.
