Organic sensitization of graphene oxide and reduced graphene oxide thin films for photovoltaic applications

In this work, a new organic compound (K-Azo) was introduced to enhance the electrical and optical performance of graphene oxide (GO) reduced GO (rGO) nanostructured films. The improved modified chemical vapour method employed for synthesis rGO. photophysical characterization thin films performed by applying analytical techniques including X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, ultraviolet-visible, Raman spectroscopy. properties (I-V characteristic) rGO displayed higher conductivity which 4.07 × 10?7 1.10 10?3 S/cm, respectively in presence sensitizer. However, showed 9.91 6.17 10?4 absence K-Azo Optical investigations indicated that characteristics were due long-range ?-electron delocalization sensitizer contributed potential photovoltaic solar cell applications.
