Abstract: A composite dye-sensitized solar cell comprises a conductive substrate, and also a nanoparticle compact layer, a nanotube layer and a nanoparticle scattering layer which are stacked on the conductive substrate sequentially, and further an auxiliary electrode stacked on one side of the nanoparticle scattering layer far away from the conductive substrate, and a composite dye and an electrolyte filled into a space between the conductive substrate and the auxiliary electrode. The composite dye includes at least one short-wavelength light absorption dye and at least one long-wavelength light absorption dye. The nanoparticle compact layer can increase the contact area with the composite dye and further enhance the power generation efficiency. The nanotube layer can transmit the generated electric energy to the external electrodes efficiently. The composite dye can absorb light with different wavelength ranges. Therefore is effectively improved the photovoltaic conversion efficiency of the dye-sensitized solar cell (DSSC).
