Description

  • The invention relates to a solar module with the features in the preamble of the main claims.
  • Photovoltaic solar modules are known in practice, which have a multilayer structure and consist of a glass pane, a matrix of solar cells and a rear foil-like cover layer. Between the three layers transparent films of ethylene vinyl acetate (EVA) are arranged, which connect the adjacent layers together. The EVA poles age over time, affecting light transmission and reducing module performance. In addition, a considerable production effort is required for a bubble-free film order, wherein z. B. with strong suction the air must be sucked out of the connection and contact areas.
  • It is an object of the present invention to show a better solar module.
  • The invention solves this problem with the features in the independent claims.
  • The bonding compound for embedding solar-active elements, in particular solar cells or hybrid arrangements, has the advantage that they replace the EVA films and provide a secure and translucent connection between a transparent support and a layer of at least one solar-active element, eg. B. a photoactive solar cell or a hybrid arrangement can form. The one or more solar-active elements can be embedded in the bonding compound and enclosed by it on several sides. This also ensures a seal of the solar-active elements against environmental influences, in particular air and moisture access. This is particularly advantageous on the edge regions of the solar module, which can be sealed and sealed better than before.
  • The compound compound is initially yielding and can dodge or be compressed, for what z. B. a pasty or liquid consistency is advantageous. But also compressible films can be used. After embedding of the solar active elements or the bonding compound can solidify by z. B. hardens, which is possible by component reaction of a multi-component material, by light curing or otherwise. By solidification of the entire layer composite is stabilized and the connection effect, in particular an adhesive or adhesive effect of the bonding compound generated or stabilized.
  • The bonding compound can be applied more easily and safely bubble-free by their compliant consistency. In particular, air gaps between the solar active element and the transparent support can be avoided. This is an advantage, although not essential. In particular, the bonding compound can form a full-surface and very thin contact layer in the connection region. This can be advantageous for avoiding power-reducing reflections or refractions of the incident light rays.
  • The claimed production technique has the advantage that the controllable and relaxable curvature of one or more layers, in particular of a carrier, a uniform and secure distribution of the flexible compound compound, in particular in pasty or liquid form, can be achieved. By a mutual pressing of the layers to be joined and the relaxation of the curvature, a rolling and distribution effect on the previously applied bonding compound can be achieved. The displacement of the bonding compound can also favor the embedding and multi-sided encircling of the solar-active element.
  • For the supply of another layer and the mutual pressing of the layers with the intermediate bonding compound, a handling device may be advantageous, which has a multi-axis mobility and which in particular includes a multi-axis manipulator, preferably an industrial robot. By the handling device, the handling operations within the manufacturing facility can be simplified and accelerated. In addition, additional functions can be carried out as needed via such a handling device, in particular a control and testing of solar-active elements and their connection and, if appropriate, the production of such an electrically conductive connection by means of soldering or the like.
  • The carrier with a solar active element embedded and connected via the bonding compound may constitute a basic component for the production of different types of solar modules. The production technology used for this can always be the same, so that large numbers and a high level of economy can be achieved in the manner of a modular system. The further manufacturing processes can be module-specific and depend on the type of solar-active elements.
  • For the further manufacturing steps, it is also advantageous to use an application technique and an application device, which also applies one or more further layers to the base component with the aid of a rolling process. This z. B. a flexurally elastic cover layer in Film form are rolled, wherein in the Wälzzwickel or rolling gap, a fluidic adhesive is introduced and distributed at the same time.
  • The nature and structure of the further layers may vary. The cover layer may, for. B. be mentioned flexible film. Alternatively, it may be a stabilizing plate, e.g. B. a glass plate.
  • The claimed production technology can also be used for other types of solar modules z. B. with heat absorbing layers or bodies as a solar active element or in addition to such are available. Also vapor-deposited or printed solar-active elements on a transparent support can be processed and connected by means of manufacturing technology with plate-shaped cover layers by means of their curvature and introduction of a bonding compound.
