Latest Patents

The standout patent attributed to Yutaka Niizawa is titled "Method of manufacturing solar battery." This innovative method involves preparing a layer-shaped member composed of a substrate, a first electrode layer, a CIS layer, and a second electrode layer. The process sets the temperature of this layered member to a specific second temperature, which is lower than the first. It then entails forming a layer of a layer-forming substance with a higher linear expansion coefficient than the substrate in solid state on the second electrode layer. Upon cooling, the layer of material allows for the effective peeling of the CIS layer from the first electrode layer, facilitating the production of a thin-film CIS solar battery.
