摘要: In this study, dye-sensitized solar cells (DSSC) were fabricated using graphene-TiO2 composite photoanodes. The nanocomposites prepared the heterogeneous coagulation between Nafion-coated graphene and commercial TiO2 (P25) nanoparticles, which ensured a tight interfacial binding them. DSSC incorporating 0.5 wt % in photoanode demonstrates power conversion efficiency of 4.28%, is 59% higher than that without graphene. It was found incorporated caused both increased dye adsorption significant longer electron lifetime. Graphene has been proven to be an attractive candidate for improving performance DSSC.
