  • Patent number: 8911231
    Abstract: A substrate-treatment installation includes a vacuum chamber, a substrate treatment device within the vacuum chamber, a substrate transport device within the vacuum chamber for guiding a substrate along a longitudinal direction in a substrate transport plane past the substrate treatment device, and a device for controlling substrate temperature. The substrate temperature controlling device includes a heat-absorbing cooler on one side of the substrate transport plane and an insulation member selectively displaceable between at least two different positions to vary extent of thermal shielding of the heat-absorbing cooler relative to the substrate transport plane by the insulation member.

  • Patent number: 8828194
    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.

  • Patent number: 8669463
    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.

  • Patent number: 8197222
    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: 20120118541
    Abstract: A device for controlling the temperature of substrates in a substrate-treatment system, in which a substrate can be guided in the longitudinal extension of the substrate-treatment system in a substrate transport plane within a vacuum chamber past a treatment device, solves the problem of dynamically shaping a dynamic change of the thermal insulation to control the heat transfer in the substrate and thereby, reduce, in particular, thermal inertias by providing a heat-absorbing cooler side of the substrate transport plane. The heat-absorbing cooler can be shielded, at least partially from the substrate transport plane, using an insulation member.

  • Publication number: 20120024363
    Abstract: A thin-film solar cell includes a front-side glass substrate, a front contact arranged above the glass substrate, an absorber arranged above the front contact, and a rear contact arranged above the absorber. A TCO layer system composed of an intrinsic TCO layer deposited above the substrate and a doped TCO layer arranged thereabove is provided, as well as a method for producing such a thin-film solar cell. Improved transmission, reflection and absorption properties of the TCO layer is achieved by composing the TCO layer of a first doped TCO sublayer deposited directly on the intrinsic TCO layer, and a second doped TCO sublayer deposited directly on the first doped TCO sublayer.

  • 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.
