COLORING MATTER SENSITIZATION TYPE SOLAR BATTERY CELL, COLORING MATTER SENSITIZATION TYPE SOLAR BATTERY MODULE USING THE SAME, AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a coloring matter sensitization type solar battery cell, a solar battery module using it, and their manufacturing method having high power generation efficiency, mass productivity, and economical efficiency. SOLUTION: This coloring matter sensitization type solar battery cell 100 is laminated with at least a transparent substrate 1, a transparent electrode layer 2, a power generation layer 8, a back electrode layer 5, and a back substrate 6 in this order from the light receiving face side. For a layered product of the power generation layer 8 and below, the back substrate 6 used as a base material is pattern-coated with a platinum paste to form the back electrode layer 5, it is pattern-coated and baked with a coating liquid of oxide fine grains having the grain size of 0.1 nm-10 m, in which at least 30 wt.% has the grain size of 0.1-10 nm, to form an oxide semiconductor film 4, it is impregnated, dried, and carried with a solution of a pigment sensitizer, then an electrolyte solution 3 is injected and impregnated to form the layered product. TiO2 fine grains are preferably used for the oxide fine grains, and a ruthenium complex is preferably used for the pigment sensitizer.
