摘要： There is described a colored photovoltaic cell (1) with a semiconductor, preferably silicon, which has high efficiency and a pleasing colored appearance, allowing it to be used as a dial for a watch or another electronic apparatus powered by the cell. The cell includes a reflective metal substrate (2) serving as the bottom electrode, a stack of hydrogenated amorphous silicon layers forming p-i-n junctions (8), and a transparent top electrode (9). The latter may be coated with a layer (16) of slightly diffusing lacquer, which may be colorless or colored. The respective thicknesses e1 of the top electrode and e2 of the silicon are combined as a function of the refractive indices of the materials so as to produce an interferential reflection in a predetermined reflection spectrum.

摘要： A photovoltaic element comprising a p-type semiconductor layer and a transparent conductive layer comprised of indium tin oxide bonded to each other at a surface is provided. The sum of tin oxide content and tin content of the transparent conductive layer varies in the layer thickness direction and is lowest at the bonding surface of the p-type semiconductor layer and the transparent conductive layer. Thus provided is a photovoltaic element which has a high photoelectric conversion efficiency with decreased reduction even when exposed to an intense light for a long period.

摘要： A powder glass solution is applied on top of a solar cell 12 with electrodes 17 formed thereon, and solvent is volatilized, followed by baking process, by which a glass 13 is directly formed on the top of the solar cell 12. In this way, the alignment between solar cell and glass as well as the finish work of removing overflowed adhesive are eliminated. Also, by selecting a powder glass having a coefficient of thermal expansion generally similar to that of a P-type silicon substrate 14, distortion by heating due to abrupt temperature changes is reduced. Thus, cost reduction and reliability improvement can be fulfilled.
