Abstract
A dye-sensitized solar cell with high conversion efficiency is provided. The dye-sensitized solar cell according to the present invention has, between an electrode (2) formed on a surface of a transparent substrate (1) and a counter electrode (6), a light-absorbing layer (3) containing light-absorbing particles carrying dye and an electrolyte layer (5), characterized in that the light-absorbing layer (3) containing light-scattering particles (4) different in size from the light-absorbing particles. In such a dye-sensitized solar cell according to the present invention, the energy of light, which passes through a light-absorbing layer in a conventional cell structure, can be strongly absorbed by the dye in the light-absorbing layer of the present invention. This will increase the conversion efficiency and output current of the dye-sensitized solar cell.
