  • Publication number: 20110108105
    Abstract: A method is provided for depositing a transparent conductive oxide (TCO) layer on a substrate, in which contaminations of the layers of the layer system is reduced through the diffusion of material from the substrate, and whose layer properties in respect to coupling and transmission of light are optimized. For that purpose, a barrier layer, a seed layer and a transparent conductive oxide layer are directly successively deposited on the substrate. Also, a thin-film solar cell is described which comprises such a transparent conductive oxide layer.

  • Publication number: 20100291393
    Abstract: A layer system that can be annealed comprises a transparent substrate, preferably a glass substrate, and a first layer sequence which is applied directly to the substrate or to one or more bottom layers that are deposited onto the substrate. The layer sequence includes a substrate-proximal blocking layer, a selective layer and a substrate-distal blocking layer. Also provided is a method for producing a layer system that can be annealed and has a sufficient quality even under critical climatic conditions and/or undefined conditions of the substrate. During the heat treatment (annealing, bending), the color location of the layer system is maintained substantially stable and the color location can be widely varied at a low emissivity of the layer system. For this purpose, a first dielectric intermediate layer is interposed between the substrate-proximal blocking layer and the selective layer and is configured as a substoichiometric gradient layer.

  • Publication number: 20100239762
    Abstract: An apparatus is provided for introduction and/or removal of a substrate into and/or from a process chamber of a vacuum coating unit that includes a process region adjoined by a lock chamber separable from surrounding atmosphere and from the process region by vacuum-tight lock gates. The process region encompasses a process chamber and a transfer chamber for altering transport speed. A vacuum-tight gate on the inlet side of a lock system is opened, the substrate is transported into the lock system and the gate is closed. Pressure in the lock system is subsequently matched to pressure in a subsequent space. An outlet-side gate of the lock system is opened and the substrate is transported from the lock system. The lock system includes a lock chamber and the adjoining transfer chamber. A passage between the transfer chamber and lock chamber remains open during introduction or removal of the substrate.

  • Publication number: 20090202362
    Abstract: A highly efficient getter pump with low maintenance requirements is applied to a vacuum coating installation, allowing a substrate to be coated to remain uncontaminated by a dusting of getter material. The getter pump comprises a pump housing with an exposure opening. The housing has a getter body, of getter material that essentially closes the exposure opening and can move in relation to the exposure opening. An inner sub-section of the surface of the getter body points towards the interior of the pump housing and an outer sub-section points towards the exterior of the pump housing through the exposure opening. The positions of the inner and outer sub-sections are interchangeable by movement of the getter body. The getter pump is equipped with a device for removing getter material from the inner sub-section.

  • Publication number: 20060225652
    Abstract: The invention concerns an apparatus for vacuum coating of substrates of various sizes that consists of lock chambers at the entrance and at the exit and several processing chambers arranged one behind the other as well as of a conveying system for the sequential transport of substrates with a certain substrate width through the lock chambers and for their continuous transport through the coating chambers. The lock and processing chambers each have a chamber width that corresponds to the substrate width, and the lock chamber is characterized by a loading area AL having a width b and a length l that indicates the size of substrate that can be accommodated. The object of the apparatus according to the invention is to better utilize the coatable area of each processing chamber so that less coating material is wasted. The object is solved by making the ratio R of width to length R=w/l greater than a minimum ratio Rmin where Rmin =0.95?0.019 AL.

  • Patent number: 6942768
    Abstract: A system for coating band-shaped material, where the band-shaped material travels through at least one process chamber in which there is a vacuum, and at least one cooling roller. On the peripheral surface of each cooling roller are at least two magnetron sputter sources that are arranged separate from one another in magnetron chambers, which are formed by separate magnetron chamber walls and allow each chamber to be evacuated, so the pressure in the magnetron chamber can be maintained higher than that in the process chamber. The magnetron chamber walls and the magnetron sputter sources can be mounted on a common carriage, which is displaceable parallel to the cooling roller axis. The result is the reduction in the maintenance costs in cleaning of the magnetron chamber walls and at the same time improvement of the separation of gas between the magnetron chambers and the process chamber.
