Latest Patents

Kura's latest patents focus on the development of photovoltaic devices that incorporate multiple interconnected photoelectric cells. One of his key inventions involves a method of fabricating a three-dimensionally shaped photovoltaic device. This process begins with the formation of a photovoltaic element on a flexible substrate while it is flat. The substrate is then deformed to achieve the desired three-dimensional shape. A crystalline photovoltaic conversion layer is formed on the flat substrate, which is subsequently cut or divided while leaving the substrate uncut. This results in a plurality of separate adjacent photovoltaic elements on the substrate. The cutting process can be executed using laser irradiation. The deformation can be achieved by utilizing a shape memory member as the substrate or by bonding a shape memory member onto the substrate. This allows for the restoration of the shape memory member to its previously memorized three-dimensional shape. The adjacent photovoltaic elements can be electrically interconnected in series by applying bond wires or an insulating film followed by a conducting film in the cut regions between the elements.
