Abstract
H2O2supported carbon nanoparticles were synthesized through hydrothermal treatment. The Fluorescent Carbon Nanoparticles (FCNs) could be easily functionalized with H2O2 and showed blue emission fluorescence with higher stability in aqueous solution. The FCNs were characterized using absorption spectroscopy, Fluorescence spectroscopy, Fourier-transformed Infrared spectroscopy, Field Emission Scanning Microscopy, and Transmission Electron Microscopy. The synthesized FCNs were subsequently applied in dye sensitized solar cells to enhance the efficiency of the solar cells. The essential photovoltaic parameters, such as open circuit voltage (VOC), short circuit current density (ISC), fill factor (FF), and the overall conversion efficiency (η), were evaluated. The solar-to-electric efficiency of the fabricated dye sensitized solar cell was 0.10%. Furthermore, electrochemical impedance spectroscopy (EIS) was performed to elucidate the charge transfer and transport processes that occur in the fabricated DSSC.
