<p>PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell which exhibits little deterioration in performance due to ultraviolet rays.SOLUTION: The dye-sensitized solar cell is characterized by being provided with an ultraviolet absorbing layer outside a photoelectrode. The ultraviolet absorbing layer preferably contains an ultraviolet absorber. As the ultraviolet absorber, an ultraviolet absorber (UVA) for converting optical energy into harmless thermal energy and a hindered amine light stabilizer (HALS) for trapping radicals generated by photooxidation can be used. The dye-sensitized solar cell of the present invention is provided with the layer for absorbing ultraviolet light on an upper layer of the dye-sensitized solar cell, thereby suppressing deterioration due to ultraviolet light.</p> |
