Patent ID: 8592676

Claim:
A solar cell comprising: a transparent electrode covered by a first organic coating, a film of n-type fine silicon particles, the film of n-type fine silicon particles including at least one n-type fine particle completely covered by and in direct contact with a second organic coating, and a film of p-type fine silicon particles, the film of p-type fine silicon particles including at least one p-type fine particle completely covered by and in direct contact with a third organic coating, wherein the film of n-type fine silicon particles and the film of p-type fine silicon particles are laminated on the surface of a transparent substrate one after another, the first organic coating and the second organic coating, and the second organic coating and the third organic coating are respectively bound to each other via respective covalent bonds, at least one of the first organic coating, the second organic coating, or the third organic coating comprises a monomolecular film, and each respective covalent bond is an N—C bond formed by a reaction of a respective epoxy group.
