ABSTRACT:
A method of manufacturing a photovoltaic device, in which a plurality of photoelectric conversion elements comprising a first electrode layer, a semiconductive layer and a second electrode layer are laminatedly arranged on an insulative surface of a substrate and said photoelectric conversion elements are electrically connected in series with each other, comprising a step of dividedly arranging the first electrode layer on the surface of the substrate, a step of coating the semiconductive layer on the surface of the substrate including the upper surface of the divided first electrode layer, a step of coating the second electrode layer on the semiconductive layer, and a step of dividing the semiconductive layer and/or the second electrode layer in order to define each element by irradiating energy-beams on the semiconductive layer and/or the second electrode layer. The formation of a low resistance layer in the semiconductive layer and a residual molten second electrode layer can be prevented by using energy-beams having an energy-distribution substantially uniform over the entire irradiated zone. In addition, short-circuits between the adjacent photoelectric conversion elements can be prevented.
