NOVELTY - The method comprises forming a porous layer (12) having pores (12a) on a photoelectric conversion body (11) configured to generate photo-generated carriers upon receipt of light, and forming an electrode (12) by disposing a conductive material on the porous layer, where the conductive material infiltrates the porous layer to contact the photoelectric conversion body. The porous layer is made of a translucent or particulate metal oxide material and/or an organic material including air bubbles. The air bubbles are included in the resin material by stirring the resin material.    USE - The method is useful for manufacturing a solar cell.    ADVANTAGE - The method is capable of simply, easily, effectively and rapidly manufacturing the solar cell with line-shaped electrode that is thick and more conductive.    DETAILED DESCRIPTION - The method comprises forming a porous layer (12) having pores (12a) on a photoelectric conversion body (11) configured to generate photo-generated carriers upon receipt of light, and forming an electrode (12) by disposing a conductive material on the porous layer, where the conductive material infiltrates the porous layer to contact the photoelectric conversion body. The porous layer is made of a translucent or particulate metal oxide material and/or an organic material including air bubbles. The air bubbles are included in the resin material by stirring the resin material or by impregnating a foaming agent into the resin material and then heating the impregnated resin material up to a foaming temperature. Each pore of the porous layer has a size of 0.1-100 mu m. The method further comprises heating the porous layer for fixing the fine line-shaped electrodes, and pressurizing the porous layer to remove pores from the porous layer. The pores are formed by a laser method as through-holes in the porous layer in a direction perpendicular to a light receiving surface of the photoelectric conversion body. The conductive material is a resin-type conductive paste having conductive particles as a filler, or a sintered-type conductive paste containing conductive particles, glass frits, an organic vehicle or an organic solvent. An INDEPENDENT CLAIM is included for a solar cell.    DESCRIPTION OF DRAWING(S) - The diagram shows an enlarged cross-sectional view of a light receiving surface of a solar cell.
