Dye-sensitized solar cells (DSSCs) are fabricated using a novel 3C-SiC/TiO(2) nanocomposite as a photoelectrode to enhance the power conversion efficiency. Compared with a pristine nanocrystalline TiO(2) cell, a DSSC based on a 3C-SiC (0.04 wt%)/TiO(2) nanocomposite photoelectrode shows ~115% increase in power conversion efficiency.
