    摘要： High efficiency, thin active-layer silicon solar cells and a process for their fabrications have been provided. The cells are characterized by a capability of employing a low-cost, metallurgical grade silicon for the substrate. The substrate has a silicon dioxide barrier coating with electrical conductivity to the active semiconductor layers provided by a multiplicity of fine holes through the oxide. The holes have silicon therein to afford electrical continuity between the active layers and the silicon of the substrate. The process comprises in situ formation of silicon dioxide on the silicon, formation of the holes in the oxide by photolithography, and etching enabling nucleation and growth of silicon in the holes by epitaxy.

    摘要： A technique for manufacturing durable, reliable solar cells by a continuous process suitable for large-scale manufacture involves, in substance, providing a reel of thin metal foil substrate and forming on the substrate a series of layers operative to form a photovoltaic junction, short prevention blocking layers, contacts and integral encapsulation. The foil substrate is processed as a continuous reel substantially until final testing at which point, if desired, it can be cut into individual cells for deployment. In comparison with a batch process, the continuous technique can reduce manufacturing cost by as much as a factor of two.

    摘要： This invention relates to a high efficiency solar cell with a novel architecture. In one embodiment, the solar cell is comprised of a high energy gap cell stack and a dichroic mirror. The high energy gap cell stack is exposed to solar light before there is any splitting of the solar light into spectral components. Each cell in the high energy gap cell stack absorbs the light with photons of energy greater than or equal to its energy gap, i.e., the blue-green to ultraviolet portion of the solar light. Each cell in the high energy gap cell stack is transparent to and transmits light with photons of energy less than its energy gap. Spectral splitting is then performed by means of the dichroic mirror on the remaining light, i.e., the light transmitted by the high energy gap cell stack.

    摘要： A polycrystalline film of silicon including silicon grains having an aspect ratio, d/t, of more than 1:1, wherein “d” is the grain diameter and “t” is the grain thickness. The polycrystalline film of silicon can be used to form an electronic device, such as a monolithically integrated solar cell having ohmic contacts formed on opposed surfaces or on the same surface of the film. A plurality of solar cells can be monolithically integrated to provide a solar cell module that includes an electrically insulating substrate and at least two solar cells disposed on the substrate in physical isolation from one another. Methods for manufacturing the film, solar cell and solar cell module are also disclosed. The simplified structure and method allow for substantial cost reduction on a mass-production scale, at least in part due to the high aspect ratio silicon grains in the film.

    摘要： A thin-film solar cell is made up of semiconductor layers formed on a substrate. The substrate includes an insulator containing electrically conducting nucleation sites which is interposed between the electrical contact of the substrate and the adjacent semiconductor. The insulator can also be optically transparent. Grain boundaries and voids terminate on the insulator. The solar cell is fabricated by selectively introducing nucleation sites into the insulator layer which is formed on the substrate material, and activating the nucleation sites during growth of the semiconductor layers.
