Abstract
In a dye sensitizing solar cell 1 wherein an electrolyte 4 is filled in a space between a photoelectrode 2 and a counter electrode 3, recesses 8 are formed in the surface 5a of a substrate member 5 of the photoelectrode 2, and a transparent electrode film 6 is formed on the surface of the substrate member 5 to form recessed portions 10 in the transparent electrode film 6. On the transparent electrode film 6 of the photoelectrode 2 with this construction, a porous semiconductor electrode film 7 is formed, and a sensitizing dye is absorbed and carried on the porous semiconductor electrode film 7.
