Abstract:
A method of manufacturing a solar cell having a plurality of solar cell elements that are formed by a transparent conductive film, an amorphous silicon film, and a metallic electrode film on a substrate, said solar cell elements being in mutual proximity,wherein after a step which continuously laminates said transparent conductive film, said amorphous silicon film, and said metallic electrode film in this sequence on the substrate, patterning is performed of the laminate by using photolithography technology;wherein said patterning is performed by one photoresist film application step and two etching steps;said method further comprising a photoresist film patterning step whereby an aperture and at least two mask parts, each having a different thickness from each other, are formed in the photoresist film formed by the photoresist film application step; andwherein in said photoresist film patterning step, a mask part that has a thickness that is smaller than that of another mask part in said photoresist film is disposed so as to be adjacent to the aperture that is formed in the photoresist film.
