PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell having high power generation efficiency, excellent mass productivity and economical efficiency, a solar cell module using the same, and a method of manufacturing the same. SOLUTION: A dye-sensitized solar cell 100 is formed in a structure in which a transparent substrate 1, a transparent electrode layer 2, a power generation layer 8, a back electrode layer 5, and a back substrate 6 are sequentially stacked at least from the light receiving surface side. , The laminated body of the power generation layer 8 or less Is coated with, for example, a platinum paste to form a back electrode layer 5, and a coating liquid of mixed fine particles obtained by mixing 1 to 50 wt% of oxide fine particles having a particle diameter of 0.1 nm to 10 μm and fine particles having a high light diffusing ability on the back electrode layer 5. Is provided by pattern-coating and baking, and a solution of the dye sensitizer is impregnated in the oxide semiconductor film 4, dried and supported, and then the electrolyte solution 3 is injected and impregnated. Formed. It is preferable to use TiO 2 fine particles as the oxide fine particles and fine particles such as inorganic beads or fillers as the fine particles having high light diffusing ability. |
