    摘要: A process and apparatus (70) for making a large area photovoltaic device (22) that is capable of generating low cost electrical power. The apparatus (70) for performing the process includes an enclosure (126) providing a controlled environment in which an oven (156) is located. At least one and preferably a plurality of deposition stations (74,76,78) provide heated vapors of semiconductor material within the oven (156) for continuous elevated temperature deposition of semiconductor material on a sheet substrate (24) including a glass sheet (26) conveyed within the oven. The sheet substrate (24) is conveyed on a roller conveyor (184) within the oven (156) and the semiconductor material whose main layer (82) is cadmium telluride is deposited on an upwardly facing surface (28) of the substrate by each deposition station from a location within the oven above the roller conveyor. A cooling station (86) rapidly cools the substrate (24) after deposition of the semiconductor material thereon to strengthen the glass sheet of the substrate.

    摘要: The transporting device according to the invention, in particular for transporting sheet-like substrates through a coating installation, comprises transporting rollers which are rotatably mounted on both sides and horizontally arranged transversely in relation to the transporting direction, the uppermost surface lines of the transporting rollers defining the transporting plane, and is characterized in that the end parts of the transporting rollers have a smaller diameter than the middle part of the transporting rollers and in that baffles which are mounted displaceably in the axial direction of the transporting rollers between a first position and a second position are arranged between the end parts of the transporting rollers and the transporting plane. The fact that the baffles are mounted in an axially displaceable manner has the effect of considerably extending the cleaning intervals of the transporting device. At first the baffles are arranged in a first position, in which the end of the baffle lies underneath the substrate and, in the horizontal direction, as close as possible to the middle of the transporting roller Vapor-depositing material that gets beyond the edge of the substrate hits the baffle. During operation of the transporting device, the baffles are continuously displaced from the middle part to the ends of the transporting rollers. As a result, the increase in thickness of the layer produced on the baffles is limited, since the vapor keeps hitting new portions of the baffle.
