【 摘 要 】

A novel kind of fluorescent photonic crystal (FPC) films were prepared by co-assembly of monodispersed silica colloids and carbon dots (CDs), exhibiting brilliant structural color and excellent fluorescence simultaneously. The fluorescence spectra of FPC films have been showing a peak at 486 nm. By comparison, the dye-sensitized solar cells (DSSCs) with FPC film show higher power conversion efficiency (PCE) (4.28%) than those of DSSCs without PC film (4.08%). A relative efficiency enhancement of 4.9% was achieved, indicating that the carbon-based fluorescent photonic crystal film can be applied to enhance the efficiency of the dye-sensitized solar cell.
