| Popis: | This research demonstrates the utilization of newly designed advanced Ag/rGO/TiO2 ternary nanocomposite based photoanode for highly-efficient plasmonic dye-sensitized solar cells (PDSSCs). The Ag/rGO/TiO2 ternary nanocomposite was successfully synthesized by a facile solvothermal approach without deploying any hazardous agent. In order to achieve the higher power conversion efficiency of the PDSSCs, it was necessary to improve the electron injection rate and optical absorbance of the photoanodes. The nanocomposite was characterized by FE-SEM and TEM analyses, which disclosed that the ternary nanocomposite has been synthesized. The incorporation of Ag nanoparticles onto the TiO2 nanoparticles considerably improved the optical parameters because of the localized surface plasmon resonance (LSPR). XRD and EDX spectroscopic techniques were utilized to confirm the synthesis of Ag nanoparticles and rGO. Furthermore, thermal stability of the nanocomposite was investigated by thermal gravimetric analysis (TGA). Ag/rGO/TiO2 ternary nanocomposite based photoanode demonstrated an enhanced power change productivity of 6.87% in PDSSCs, which was 15% higher than that of the pure TiO2 nanoparticles based photoanode. In addition, an enhanced IPCE of 68% was also observed in comparison with the pure TiO2, which was found due to the remarkable conductivity of rGO. |
