    摘要： A method of fabricating a three-dimensionally shaped photovoltaic device involves first forming a photovoltaic element on a flexible substrate, preferably while it is flat, and then deforming the substrate to achieve the three-dimensional shape. Preferably a crystalline photovoltaic conversion layer is first formed on the flat substrate, then the layer is cut or divided while leaving the substrate uncut to form a plurality of separate adjacent photovoltaic elements on the substrate, and finally the substrate is deformed into the three-dimensional shape. The cutting can be carried out by laser irradiation. The deforming can be carried out by providing a shape memory member as the substrate, or bonding a shape memory member onto the substrate, and then restoring the shape memory member to its previously memorized three-dimensional shape. The adjacent photovoltaic elements can be electrically interconnected in series with each other by applying bond wires or an insulating film and then a conducting film in the cut regions between adjacent photovoltaic elements.

    摘要： 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.

    摘要： A metallic insulative substrate having its surface coated with an insulative layer, on which a large number of photoelectric converter elements are electrically connected to each other in series by connecting the first back electrode layer of one of photoelectric converter elements adjoining each other with the second back electrode layer of the other. Accordingly, electrical connection of these electrode layers in series does not affect the effective area used for photoelectric conversion. This constitution also improves heat resistance of the insulative substrate. Electrical contact of the transparent light-receiving electrode layer) and the second back electrode layer is achieved via contact holes each having a diameter identical to the diameter of those of the insulative and semiconductive layers. As a result, a sufficient insulative distance is provided between the transparent electrode layer and the first back electrode layer so that occurrence of accidental shortcircuit can be securely prevented.

    摘要： An amorphous silicon film having a PIN junction inside in parallel to the film surface is formed extending continuously over transparent film electrodes in each plurality of regions being formed and spaced from each other on one main surface of a light transmissive substrate. A laser beam having a wave length covering a substantially ultraviolet rays region and a visible rays region is irradiated from the other main surface side of the light transmissive substrate to an adjacent spacing portion where the amorphous silicon film is to be divided and the amorphous silicon film lying therein is removed, thus the amorphous silicon film is divided into each plurality of regions. An aluminum electrode film is formed continuously covering the amorphous silicon film portions in each region. The laser beam is irradiated from the other main surface side of the light transmissive substrate to the adjacent spacing portion where the aluminum electrode film is to be divided and the aluminum electrode film lying therein is removed, thus the aluminum electrode film is divided in each plurality of regions. The divided aluminum film electrodes are connected to the transparent film electrodes in the adjacent regions, accordingly a plurality of photoelectric converting regions formed on the light transmissive substrate are connected in series.
