The Effect of Diatomite on the Photoelectric Properties of TiO₂ Dye Sensitized Solar Cells

Abstract:

Diatomite/TiO₂ composite films were prepared with diatomite and P25 TiO₂ nanoparticles on conductive glass substrates. The surface morphology and phase composition of the film were characterized with scanning electron microscopy (SEM) and X ray diffraction (XRD). It is concluded that diatomite doped into the film will form granular cores. Dye sensitized solar cells (DSSC) were fabricated with the diatomite/TiO₂ composite film as anode, and the photoelectric properties of the cells were tested. Results show that the doping of diatomite can significantly increase the open circuit voltage and short circuit current of DSSC. Optimized photoelectric properties can be acquired as 1.3 percent diatomite doped in TiO₂ film.
