PROBLEM TO BE SOLVED: To provide a solar cell in which transmission of carbon is prevented and the carbon does not directly contact the transparent conductive membrane installed on the photo-electrode side, and, after firing and installation on the solar cell, electrical potential is generated between the photo-electrode and the counter electrode when light is irradiated on it and performs completely as a battery, and which has improved yield of manufacture and improved conversion efficiency. SOLUTION: This is a dye sensitization type solar cell in which a transparent conductive membrane 31 is laminated on a glass substrate 31 and a first photo-electrode 34 made of a dense material is laminated on the transparent conductive membrane 32, and a second photo-electrode 35 made of a porous material is laminated on the first photo-electrode 34, and a separator 36 made of a porous material is laminated on the second photo-electrode 35, and a counter electrode 37 made of a porous carbon layer is laminated on the separator, and a photo-sensitization dye is carried by the above first photo-electrode 34 and the second photo-electrode 35, and an electrolyte is filled between the above transparent conductive membrane 32 and the counter electrode 37. The mean particle size of the constituting particles of the first photo-electrode 34 is smaller than the mean particle size of the constituting particles of the second photo-electrode 35. |
