Tadashi Hisamatsu is a prominent inventor based in Kashihara, Japan. He has made significant contributions to the field of solar technology, holding a total of 6 patents. His work focuses on improving the efficiency and manufacturability of solar panels, particularly for use in space.
Latest Patents
His latest patents include a solar panel designed for space applications and a method for manufacturing the same. The objective of this invention is to facilitate the easy and quick manufacture of solar panels intended for space use and their subsequent repairs. The solar panel is constructed by detachably linking multiple unit solar cell modules, which consist of several solar cells and connection wires. This modular approach allows for the straightforward assembly of standardized unit solar cell modules, significantly reducing the time required for manufacturing or repairing solar panels.
Another notable patent involves a solar cell with a bypass function and a multi-junction stacked type solar cell with a bypass function. In this design, island-like p regions are formed at the boundary between the p-type and n-type regions of the substrate. This innovative structure eliminates the need for an insulating film to separate the p regions from the n electrodes, thereby lowering manufacturing costs. As a result, a cost-effective bypass-function solar cell can be produced through a simplified process.
