Abstract

The present invention relates to a structured encapsulation film for a shingled photovoltaic module made of a thermoplastic material and to the use of this encapsulation film in photovoltaic modules. Furthermore, the invention relates to methods for producing a photovoltaic module having at least two shingled solar cells and photovoltaic modules having at least two shingled solar cells.

Description

  • The present invention relates to a structured encapsulation film for a shingle-type photovoltaic module, to photovoltaic modules containing this structured encapsulation film, to processes for producing these modules, and to the use of structured encapsulation films in photovoltaic modules.
  • Usually, solar cells are electrically connected in series because the resulting cell strings provide a higher modulus voltage, and these strings are laminated between two encapsulants and two cladding layers to photovoltaic modules. If the solar cells are contacted via a shingle connection to cell strings, it is possible to produce photovoltaic modules with particularly small inactive module surfaces and thus high efficiencies. For this type of connection, a generally pasty mass, in particular electrically conductive adhesive, must be cured in a precisely dimensioned joint between two partially overlapping solar cells. Alternatively, a solder joint must be produced in this joint, in particular based on solder pastes or solder deposits. Furthermore, the supernatant of adjacent cells must be kept as small as possible in order to cover little cell surface.
  • Moreover, in order to realize the smallest possible, inactive gap between adjacent strings, or to achieve an offset shingling, the position of the cells should be exactly matched transversely to the string direction. Some solar cell modules with shingled connections and methods for their production are already known from the prior art.
  • DE 4030713 A1 relates to a photovoltaic solar generator whose solar cells have contact terminals at the longitudinal edges and are combined in overlapping form to form a shingle string, wherein a plurality of shingle strings are preferably embedded between a carrier and a cover in hot melt adhesive films.
  • DE 3942205 A1 describes methods for producing a photovoltaic solar generator, the solar cells have over the cell width extending contact elements and are summarized in shingled form to shingle strings, the shingle strings are embedded between a carrier and a cover in hot melt adhesive films. The method is characterized by the following method steps: a) a paste-type contacting agent is applied to the contact elements of the solar cells, which causes an electrically conductive connection of two superimposed contact elements of two adjacent solar cells in a low-temperature vacuum process, b) the solar cells are on a support c) the shingle strings are electrically conductively connected to one another in their edge regions and equipped with electrical connections, d) the shingle strings are provided with a second hotmelt adhesive film and a second hotmelt adhesive film Cover covered, and e) in a temperature-vacuum process, the contact elements of adjacent solar cells are electrically connected to each other and almost immediately thereafter the carrier , the hot melt adhesive films, the solar cells and the cover to a solar cell generator mechanically bonded together.
  • US 2015/0349174 A1 relates to a highly efficient configuration for a solar cell module containing solar cells shingled to form supercells. These can be arranged so that the area of the solar module is used efficiently, the series resistance is reduced and the module efficiency is increased.
  • DE 3708548 A1 relates to a solar cell module, wherein the plurality of solar cell existing solar cell rows are arranged overlapping such that the joints of adjacent solar cell rows are offset from each other, with a parallel and serial interconnection is made possible within the solar cell module.
  • However, the shingled solar cell modules of the prior art still have some disadvantages. In order to make an exact definition of the gap height for the connecting material or to determine the position of the cell, the cells had to be arranged in a template, firmly connected and then deposited as a long string on the encapsulating film. The rearrangement of a finished string is complex and can lead to fractures, especially if the strings are also aligned with each other or a displacement of the cells is sought across the string direction.
  • On this basis, it was an object of the present invention to provide an encapsulating film which permits a precise definition of the gap height for the connecting material and which furthermore allows the overlapping width of adjacent cells to be defined exactly. A very small overlap between adjacent cells ensures higher module efficiency. A further object of the present invention was to provide a simpler manufacturing method of photovoltaic modules with shingled solar cells, which allows mounting directly on the module film, whereby the use of a additional stringer is not necessary. Furthermore, the string / lamination process should be feasible integrally (in a common process). In addition, a sub-task of the present invention was to allow a precise metering of the connecting material and thus minimizing the hidden cell surfaces. Furthermore, it was an object of the present invention to provide photovoltaic modules having little or no inactive gap of adjacent strings. To avoid this gap, in particular for an offset shingles, it is necessary to align the solar cells of adjacent cell strings also transversely to the string direction exactly.
  • This object is solved by the encapsulation film for a shingled photovoltaic module according to independent claim 1, which consists of a thermoplastic material, wherein the encapsulation film has a structuring on a surface which allows positioning of solar cells with defined overlap.
