Patents by Inventor Hidekazu Shuto

Hidekazu Shuto has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6471816
    Abstract: In this method of solar battery output section fabrication, a metal foil is attached to an output terminal on a substrate surface, or a resin film is disposed over a conductive paste as the output terminal on the substrate surface. Subsequently, an opening is cut-out from the back side of the substrate to the metal foil or the conductive paste with a periphery cutter. Or, after the metal foil and a front side protective film is provided over the output terminal on the substrate surface, an opening is cut-out from the surface of the front side protective film to the metal foil with a periphery cutter.

  • Patent number: 6365431
    Abstract: This invention manufactures a photovoltaic device by the following process steps: a step to form a first electrode layer and a light-active semiconductor layer on an insulating surface of the substrate; a step to form a transparent conducting film over most of the insulating surface including the light-active semiconductor layer; a step to establish a patterned transparent protective layer on the transparent conducting film over power generating regions; and a step to irradiate ultraviolet laser light over most of the substrate to remove exposed portions of the transparent conducting film not masked by the pattered transparent protective layer and form a transparent conducting layer corresponding to the pattered transparent protective layer. The patterned transparent protective layer serves a dual purpose as masking material for removing the specified areas of the transparent conducting film by ultraviolet laser and as a transparent protective layer.
