    摘要: A valve for isolating the interior of a glow discharge chamber from the atmosphere and other reactants. The valve includes a body mounted in an aperture of the chamber. A slit-like opening is provided therein to allow the interior of the chamber to communicate with interrelated elements of a deposition system. A source is provided for introducing inert gas into the opening under pressure somewhat greater than that of reaction gases and plasma within the chamber to create an effective, non-reactive gas curtain.

    摘要: A photovoltaic panel for converting light into electrical energy has enhanced energy conversion efficiency stability. The panel includes a photovoltaic device having an active region formed from a semiconductor material which exhibits an energy conversion efficiency stability directly related to the operating temperature of the device. The panel also includes means for maintaining the operating temperature of the device upon exposure to light at an elevated temperature above the ambient temperature external to the device. The active region semiconductor material is preferably an amorphous semiconductor alloy such as, for example, an amorphous silicon alloy. The operating temperature elevating means can include a thermal insulating material such as glass wool, styrofoam, or cork applied to the back side of the device to minimize heat conduction from the device. The panel can also include an enclosure for enclosing the device having a transparent cover overlying the device to seal the enclosure and provide a still air space adjacent the device. The panel is thereby arranged to maintain the operating temperature of the device at a temperature which is from about twenty degrees Centigrade to about one hundred and fifty degrees Centigrade above the ambient temperature external to the device.

    摘要: An apparatus and process utilizes microwave energy for depositing amorphous alloy materials in layered form onto a receiving surface. The process results in materials having unique properties suitable for many applications including photovoltaic applications. The process includes the steps of providing at least one source of microwave energy, providing at least two reaction gases, each gas containing at least one alloying element to be deposited onto the receiving surface, and selectively exciting the reaction gases with microwave energy to create excited species containing the alloying elements to be deposited for depositing the alloys in alternating layers onto the receiving surface. For depositing alternating layers of silicon and germanium alloys, the reactions gases can include silane (SiH.sub.4) or silicon tetrafluoride (SiF.sub.4), and germane (GeH.sub.4) or germanium tetrafluoride (GeF.sub.4). In accordance with one disclosed embodiment, the reaction gases are excited separately with the excited species therefrom being sequentially introduced to the receiving surface for layered deposition. In accordance with another disclosed embodiment, the reaction gases are premixed to form a mixture and thereafter, the reaction gases are selectively excited in a plasma which is moved back and forth in the direction of flow of the reaction gas mixture to form selective excited species. Layered deposition results as a consequence of both the selective depletion of one alloying element bearing species from the gas mixture flow and from the motion of the plasma excitation zone relative to the receiving surface.

    摘要: Systems and methods for detecting and eliminating latent and existing short circuit current paths through photovoltaic devices of the type including at least one semiconductor region overlying a substrate and a layer of conductive light transmissive material overlying the at least one semiconductor region are disclosed. The latent paths are first converted to existing short circuit current paths by applying a bias voltage to the devices. The short circuit current paths which are eliminated extend through the at least one semiconductor region from the substrate to the layer of conductive light transmissive material. The resistivity of the short circuit current paths is increased substantially at the interface between the conductive light transmissive material and the semiconductor region by isolating electrically the conductive light transmissive material from the short circuit current path.The isolation can be provided by removing the transparent conductive material from electrical contact or connection with the short circuit current path. The isolation also can be provided by depositing a body of insulating material onto the semiconductor region over an area including a short circuit current path prior to the deposition of the conductive light transmissive material. Further, the short circuit current path can be detected and located by applying a voltage to discrete areas of the device through a conductive solution which path then can be eliminated as described above.

    摘要: A vertical processor for the continuous deposition of semiconductor alloy material by glow discharge techniques. The vertical processor includes a plurality of operatively interconnected deposition chambers, at least one chamber of which includes a generally vertical cathode plate about each of the opposed faces of which a plasma region is developed and a substrate continuously passes for the deposition of semiconductor alloy material thereonto. Through the utilization of the vertical deposition scenario, the length of the processor may be substantially foreshortened, power consumption may be substantially decreased and feedstock gases may be more efficiently utilized.

    摘要: A continuous system for depositing at least one layer of amorphous semiconductor material upon a substrate. Feed and takeup sections provide reel-to-reel advancement of a thin film substrate through the system. At least one chamber is located between the feed and takeup sections. A plasma is generated therein by glow discharge decomposition of an appropriate mixture of reaction gases. Apparatus associated with the chamber allows the close regulation of the plasma/substrate surface equilibrium to assure the deposition of a uniform layer of amorphous material. At least one servocontrolled reel drive regulates the tension of the web-like substrate as it advances to avoid cracking and to assure its proper registration with a mask comprising a plurality of strips. A curtain of inert gas provides isolation between the interior of each chamber and the environment.

    摘要: A method for introducing sweep gas through a baffle system adapted for use with glow discharge deposition apparatus in which successive amorphous semiconductor layers are deposited on a substrate. The deposition apparatus includes at least a pair of adjacent dedicated deposition chambers into each of which different process gases are introduced, the chambers being operatively connected by a gas gate. Inert gases are swept through the gas gate to minimize back diffusion of process gases from the chambers. The baffle system is adapted to prevent said sweep gases from entering into turbulent flow when traveling through the gas gate passageway. Further, a sufficient volume per unit time of sweep gas is introduced to insure that some sweep gas flows into the cathode region of the first chamber, thereby substantially preventing process gases and plasma from escaping from the cathode region and forming silane powder.
