  • Publication number: 20060162763
    Abstract: A photoelectric conversion element is disposed in each of a plurality of recesses of a support. Light reflected by the inside surface of the recess shines on the photoelectric conversion element. The photoelectric conversion element has an approximately spherical shape and has the following structure. The outer surface of a center-side n-type amorphous silicon (a-Si) layer is covered with a p-type amorphous SiC (a-SiC) layer having a wider optical band gap than a-Si does, whereby a pn junction is formed. A first conductor of the support is connected to the p-type a-SiC layer of the photoelectric conversion element at the bottom or its neighborhood of the recess. A second conductor, which is insulated from the first conductor by an insulator, of the support is connected to the n-type a-Si layer of the photoelectric conversion element.

  • Patent number: 4758399
    Abstract: A method of forming a substrate for manufacturing single crystal thin films, wherein the substrate is a replica pattern of a monocrystalline or single crystal cleavage plane. Such replica pattern may be formed by pressing a material in a softened state against the cleavage plane of the single crystal, with subsequent hardening, and also, by subjecting the single crystal cleavage plane to vapor deposition or plating, and thereafter removing the formed layer from the single crystal cleavage plane.
