Investigating a sulfonate-rich carbon dot as a sensitizer in dye-sensitized solar cells
Carbon dots (CDs) synthesized using the direct heating method were examined as potential sensitizers in dye-sensitized solar cells (DSSCs). The energy gap (Eg) of green, yellow, orange, and red emission CDs (G-, Y-, O-, and R-CDs) was modulated by varying the amount of concentrated sulfuric acid. Ultraviolet-visible (UV-Vis) spectroscopy was employed to ascertain the Eg of these CDs. R-CD synthesized with 1.35 mL (24.82 mmol) of concentrated sulfuric acid exhibited the lowest Eg of 2.07 eV. The Lowest Unoccupied Molecular Orbital (LUMO) and Highest Occupied Molecular Orbital (HOMO) of these synthesized CDs ranged from 2.98 to 3.14 eV and 5.05 to 5.60 eV, respectively. The TiO2 electrode was sensitized with R-CD under different conditions including varying time, temperature, and concentrations. The resulting DSSC exhibited an efficiency of 0.16%, a short-circuit current density (JSC) of 0.61 mA/cm2, and an open-circuit voltage (VOC) of 0.41 V. These parameters were obtained for DSSC with the TiO2 electrode sensitized with R-CD for 2 hours at 40 °C using a 10 mg/mL solution of R-CD.
