文摘
- •
Graphene nanoparticles were synthesized via modified Hummers method.
- •
Graphene –TiO2 nanocomposites were characterized to analyze their photoelectric performance.
- •
With the increase in graphene concentration red shift in absorbance peak and reduction in band gap is observed.
- •
Jsc was found to increase from 9.82 for TiO2 nanoparticles to 14.68 mA/cm2 by Gr-TiO2 nanocomposites.
- •
The conversion efficiency of 7.68% was achieved.
