Title: The Innovations of Takeshige Ichimura
Introduction
Takeshige Ichimura is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of solar energy through his innovative patents. With a total of 2 patents, Ichimura's work focuses on enhancing the efficiency and manufacturing processes of solar cells and batteries.
Latest Patents
Ichimura's latest patents include a solar cell module and a method of manufacture. This solar cell module features a transparent substrate, an overlying transparent electrode, a layer of amorphous silicon, and a metal electrode. The design allows adjacent cells to be connected in series by using a laser to divide the transparent electrode and the metal electrode into strips, creating gaps between them. The layer of amorphous silicon lies across these gaps, and the overlying portion is crystallized by a laser beam to form connections between the electrodes of adjacent strips.
Another significant patent is for a high-efficiency solar battery. This invention comprises a transparent electrode made of SnO₂, along with a semiconductor layer and a metal electrode formed in a specific order. The surface unevenness of the transparent electrode is controlled by a dual-layer structure, where the undoped SnO₂ layer has crystal grains growing perpendicular to the substrate, creating an uneven surface. A doped layer containing impurities such as F, Cl, and Sb is then deposited over the undoped layer.
