    摘要: This invention involves a method and apparatus for drawing crystalline bodies from a melt by means of an open-ended drawing nozzle which determines the cross-sectional geometry of the crystalline body. The drawing nozzle is composed of a material which is resistant to the melt. The feed of melt proceeds from a reservoir situated at the lower end of the drawing nozzle and the melt is conveyed to the upper opening thereof by capillary action. In keeping with the present invention, there is provided a drawing nozzle which has an upper opening merging into a contoured surface such that the meniscus formed at the interface between the crystalline and molten phases is freely displaceable on the contoured surface into which the upper opening discharges.

    摘要: In an exemplary embodiment, tape-shaped silicon bodies for solar cells are formed by continuous coating of a carrier body having a mesh structure. A melt bath receives the silicon melt and has a floor part with capillary openings therein for supplying the melt, the capillary openings leading perpendicularly toward the exterior of the vat and proceeding parallel to one another, and wherein a channel for the guidance of the carrier body proceeding in a horizontal direction is disposed below the melt vat in the region of the capillary openings. The guide channel for the carrier body can also be disposed above a body with capillaries proceeding parallel in a vertical direction, the body being partially immersed in the vat containing the silicon melt for the purpose of supplying the melt via the capillaries. The devices enable continuous tape drawing from a silicon melt wherein convection currents are avoided in the melt.

    摘要: Apparatus and method for asymmetrically coating a tape-shaped carrier body with crystallized silicon for further processing into solar cells. In an exemplary embodiment a carrier body in the form of a graphite mesh is to be drawn through a guide channel leading from the floor of a melt vat and is moistened by the melt. The silicon is caused to crystallize above the melt vat because of a temperature gradient generated at right angles relative to the path of the coated carrier body. The temperature gradient can, for example, be produced by means of single-sided heating, or by a plate-shaped body extending from the melt parallel to the carrier body, or by guide lips with upper boundaries exhibiting different heights and widths. The method and apparatus serve for the continuous manufacture of silicon tapes for solar cells.

    摘要: Si-crystals with columnar structures are produced by contacting a silicon melt with a melt-resistant carrier body having periodically spaced crystallization-seed centers on a surface thereof facing the melt, establishing a controlled temperature gradient at the interface between the carrier body surface and the melt so that crystallization of the melt onto the seed centers occurs and then removing the body with the adhering crystal layer from the melt. In a preferred embodiment, an elongated traveling web having a select hole pattern therein functioning as the seed centers, is utilized as a carrier body.

    摘要: A method of producing a light conducting fiber comprises the steps of providing a base member of an optical material such as glass or a synthetic glass-like material, depositing at least one optical material forming layer such as a glass forming layer or a synthetic glass-like material forming layer from a liquid phase on a surface of the base member and subsequently transforming each of the layers into a film of optical material such as a glass film or a synthetic glass-like film. The base member may be a glass tube and the optical material forming layers may be deposited on an interior surface and after the layers have been transformed into a film, the tube is collapsed into a rod and then subsequently drawn into a cladded light conducting fiber. In one embodiment of the invention, the base member is a rod and the layers are deposited on a surface of the rod which is subsequently drawn into a cladded light conducting fiber. In yet another embodiment of the invention, the base member is provided by drawing a core of an optical fiber and the method includes depositing the optical material forming layers on the core so that as the layers are transformed into the film of optical material, a cladded light conducting fiber will be produced.

    摘要: A method and device for the complete emptying of flat quartz tanks or crucibles filled with silicon melt is provided. The apparatus includes an open outlet nozzle located in a floor of the tank and a tube-shaped, rod-shaped, or channel-shaped member composed of a material that is well-wettable by silicon melt that is brought into contact with the outlet nozzle after the conclusion of the drawing process. The member is in fluid communication with a collecting vessel. The outlet nozzle is so constructed and arranged that the silicon melt adjacent at the nozzle aperture is prevented from running out during the band drawing due to the curvature pressure of its downwardly, convexly arced surface. The apparatus can be used in continuous, horizontal band-drawing of silicon for solar cells.

    摘要: A method for continuously manufacturing silicon tapes which are predominantly coated on one side of the carrier, for solar cells. In an exemplary embodiment, a carrier body consisting of a graphite network is conducted vertically upwards through a guide channel situated in the floor of a silicon melt bath and travels through a crystallization region where the molten silicon crystallizes on the carrier body. The surfaces of the guide channel at each side of the carrier path in the vicinity of the crystallization region are wetted by the molten silicon and have different dimensions in a direction at right angles to the carrier path. As a result of the differential in surface tension forces at the two sides of the path, a meniscus is formed which is asymmetrical relative to the channel opening thereby causing asymmetrical coating of the carrier body.
