NOVELTY - A solar cell comprises a transparent electrode covered by a first organic coating, an n-type fine silicon particle film covered by a second organic coating, and a p-type fine silicon particle film covered by a third organic coating form a lamination layer on the surface of a transparent substrate one after another, and the first organic coating and the second organic coating and second organic coating and the third organic coating are respectively covalently bound to each other.    USE - As solar cell (claimed).    ADVANTAGE - The method provides large-area solar cell and allows significant reduction in costs without losing the original function of fine silicon particles while using semiconductive fine silicon particles, compared to the use of conventional amorphous solar cells or silicon crystal solar cells. The method effectively increases the binding force between films; stacking the fine silicon particle films; reduces the internal resistance of the cell; simplifying and stabilizing accumulation process; accumulating at least two layers of fine silicon particle films; increases the the resistance to exfoliation; and improves light absorption efficiency. The method allows reduction in the manufacturing time.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing a solar cell involving forming a first reactive organic coating on the surface of a transparent electrode by contacting the surface of the transparent electrode to an alkoxysilane compound among a chemical absorption liquid produced from a mixture of at least a first alkoxysilane compound, a silanol condensation catalyst, and a nonaqueous organic solvent in order for the surface of the transparent electrode to react with the alkoxysilane compound; forming a second reactive organic coating on the surface of the fine silicon particles by dispersing the n-type fine silicon particles among a chemical absorption liquid produced from a mixture of at least a second alkoxysilane compound, a silanol condensation catalyst, and a nonaqueous organic solvent in order for the surface of the n-type fine silicon particles to react with the alkoxysilane compound; process of forming a third reactive organic coating on the surface of the fine silicon particles by dispersing the p-type fine silicon particles among a chemical absorption liquid produced from a mixture of at least a third alkoxysilane compound, a silanol condensation catalyst, and a nonaqueous organic solvent in order for the surface of the p-type fine silicon particles to react with the alkoxysilane compound; a process of having the transparent electrode on the surface of the transparent substrate, on which the first reactive organic coating is formed, contact the n-type fine silicon particles coated by the second reactive organic coating for reaction; forming a monostratal n-type fine silicon particle film by cleaning and removing redundant n-type fine silicon particles coated by the second reactive organic coating; forming second reactive organic coating on the film surface of the n-type fine silicon particles, contact the p-type fine silicon particles coated by the third reactive organic coating for reaction; forming a monostratal p-type fine silicon particle film by cleaning and removing redundant p-type fine silicon particles coated by the third reactive organic coating; and forming a back surface electrode.
