Abstract: A method for repairing a defective semiconductor device, the defective semiconductor device including a semiconductor thin film and a conductive thin film, disposed in the named order, on a conductive surface of a substrate, such that the conductive thin film and the conductive surface of the substrate are electrically short-circuited at a pinhole occurring in the semiconductor thin film to form an electrically short-circuited portion.

Abstract: A reflective solar cell substrate comprising a base member composed of a metallic material provided with irregularities at the surface thereof and a buffer layer disposed on said base member so as to cover the entire of said irregularities at the surface of said base member, said buffer layer being composed of a substantially transparent or translucent and conductive material, said buffer layer being provided with irregularities at the surface thereof, and said irregularities at the surface of said buffer layer comprising a plurality of thickened convex portions and a plurality of thinned concave portions, said portions being alternately arranged. The reflective solar cell substrate reflects light reaching the substrate without being absorbed by the optically active layer at an effective angle, whereby the solar cell exhibits improved photovoltaic characteristics.

Abstract: An electrophotographic light receiving member comprising a substrate and a light receiving layer having a multi-layered structure disposed on said substrate, said light receiving layer comprising at least a photoconductive layer and a surface layer being stacked in this order from the side of said substrate, said photoconductive layer being formed of a non-single crystal material containing silicon atoms as the matrix and at least one kind of atoms selected from the group consisting of hydrogen atoms and halogen atoms, and said surface layer being formed of a polysilane compound having a weight average molecular weight of 6000 to 200000 and having at least an oxygen-free organic group selected from the group consisting of alkyl group, cycloalkyl group, aryl group and aralkyl group at the terminals.

Abstract: A photosensor has a photoconductive member. The photoconductive member has a structure comprising a laminated product consisting of functional thin films superposed on one another. The laminated product comprises at least two functional thin films. The functional thin film containing 10 atomic % or less of hydrogen. The band gaps and conduction types and/or conductivity of the functional thin films are controlled to provide high photo sensitivity.
