Abstract

In this study, the highly efficient organic indoline DN350 based dye sensitized solar cells (DSSCs) have been fabricated using reduced graphene oxide (rGO)-TiO₂ composite nanofibers (NFs) and tested its photovoltaic properties. The influence of the rGO on the morphology, structural properties of the TiO₂ NFs have been characterized by various techniques. Our photovoltaic results revealed that the modified rGO-TiO₂ composite NFs exhibited higher power conversion efficiency (PCE) in comparison with the pristine-TiO₂ NFs. The electrochemical analysis indicated that the GO content provides more active sites results in higher dye adsorption which consequently improves the DSSCs performance. Our optimized sample containing 4 mg-rGO-TiO₂ NFs exhibited the best performance with 4.43% PCE, which is higher than the pristine-TiO₂ NFs (3.83%). Overall, this study presents the rGO-TiO₂ composite NFs as a novel strategy for enhancing the efficiency of the organic indoline DN350 based DSSCs.
