| Abstract: | Nano-crystalline TiO2 propous films composed of small and large TiO2 nano-particles were applied to the dye-sensitized solar cells.The results show that mixing TiO2 large nano-particles can increase adsorption capacity and light scattering of nano-crystalline TiO2 propous films,improve photoelectric output.The photoelectric conversion efficiency with the film electrode could be 5.66% irradiated by a solar simulator with100mW/cm2. |
