Plasmonic solar cells (PSC) are a type of solar cell which use the surface plasmon absorption generated by the nanoparticles. Because of the high molar absorption coefficient and chemical robustness, gold nanoparticles are widely used in this type of thin film solar cell. Here, we report a simple and one-step method of generating gold nanoparticles stabilized directly with fullerenes C60 that led to C60-AuNPs having high fullerenes C60 load and stability. C60-AuNPs are soluble in DMF or a mixture of DMF and water which was followed by characterized UV-Vis, FTIR, DLS, Zeta potential, XRD, TEM, and AFM. The C60-AuNPs were used in fabricating PSCs making a blend with TiO2 varying the ratio of C60-AuNPs to TiO2 to investigate the photo-conversion efficiency.
