METHOD FOR MANUFACTURING SOLAR CELL, AND SOLAR CELL

Document Type and Number:

WIPO Patent Application WO/2014/084133

Kind Code:

A1

Abstract:

A purpose of the present invention is to provide a method for manufacturing a solar cell, which is capable of producing a porous inorganic oxide layer that contains less impurities and has high porosity even by low-temperature firing. Another purpose of the present invention is to provide a solar cell which is manufactured using the method for manufacturing a solar cell. The present invention is a method for manufacturing a solar cell, which comprises: a step wherein an inorganic oxide paste containing inorganic oxide fine particles, a binder resin and an organic solvent is applied over a surface of a base, said surface being provided with a conductive layer, thereby forming an inorganic oxide layer on the base; a step wherein the inorganic oxide layer is fired; a step wherein a porous inorganic oxide layer is obtained by irradiating the inorganic oxide layer with an active energy ray or by subjecting the inorganic oxide layer to ozonolysis; and a step wherein a semiconductor is laminated on the porous inorganic oxide layer.
