PROBLEM TO BE SOLVED: To provide a regeneration dye sensitized solar battery which can be practically used wherein porphyrin derivatives and their metal complexes are used, and which has high photovoltaic conversion characteristics. SOLUTION: In the solar battery in which an electrolyte is filled between a pair of electrodes wherein a transparent electroconductive film having a porous semiconductor film in an inner side surface is assumed as one side of electrodes and a metal film is assumed as the other side of electrodes, and wherein a current circuit is formed between both electrodes by irradiate from the transparent electroconductive film side, at least one kind of pigment selected from porphyrin compounds expressed in a formula (R is hydrogen atom or acid substituted group) and their metal complexes is carried in fine pores of porous semiconductor film. |
