▎ 摘  要

This paper presents a novel method for ruthenium-based dye-sensitized solar cell (DSSC) power-conversion efficiency optimization, which consists of TiO2 active layer sensitization with graphene quantum dots. Under proper excitation illumination, graphene quantum-dots emit photons of wavelengths which are absorbed by the ruthenium molecules in the active layer, thus enhancing free electron generation in the DSSC structure. A power-conversion efficiency of 11 :27%, under halogen lamp illumination, is reported for ruthenium-based DSSC samples doped with graphene quantum-dots. This result represents a difference of 9:57%, compared to a reference ruthenium-based DSSC sample with 1:70% power-conversion efficiency, under halogen lamp illumination.
