Definitions
- a solar module or photovoltaic module converts the sun's light directly into electrical energy.
- the most important components are several solar cells.
- a solar module is characterized by its electrical connection values (in particular open circuit voltage and short-circuit current). These depend on the properties of the individual solar cells and the interconnection of the solar cells within the module.
- a solar module usually has in addition to the electrically interconnected solar cells an embedding material and a back construction.
- a cover layer protects against mechanical and weather influences.
- the potting material and the cover layer must be transparent in order to minimize absorption losses in the spectral range from 350 nm to 1150 nm and thus efficiency losses of the silicon solar cells usually used for power generation.

- the processing parameters (time-dependent pressure and temperature curve) for EVA are very narrow.
- EVA yellows under UV light. Molten EVA also flows into the interstices of the electrically contacted or connected to conductive adhesives solar cells and is thermally crosslinked. The formation of air bubbles leading to a reduction in the connected loads (generated by the solar module) is avoided by lamination under vacuum and / or mechanical pressure.

- the plus and minus terminal PM of the interconnected solar cells can be contacted from the side to be irradiated (through an opening in the backside film) - see FIG. 6 - and in a subsequent test station 24 with sunlight-like illumination first functional test of the far completed arrangement, the pre-laminate, can be performed.
- FIG. 8 illustrates a further variant of the method and the corresponding device as well as the resulting solar module arrangement.
- an adhesive film of TPU thermoplastic
- TPU thermoplastic
- the remaining steps do not differ from the variants described above.
- non-networked solar module composites are deposited in an input region of a step-by-step crosslinking station and entered into the crosslinking station.
- This crosslinking station shown here operates stepwise and is set by a process control device (not further shown) to expose each of its supplied solar module assemblies to a defined temperature profile in which the film webs are brought into the area of the crosslinking temperature for the required time for the first time , Further details are explained in connection with FIG. 11 below.
- the edge regions of the solar cells are insulated to the contact strips.
- one or more additional insulating material dispensers which can be modularly integrated into the overall arrangement, serve to bring insulation material as a tape or paste material or as a liquid adhesive to the respective locations of the solar cells. This is illustrated for a variant for the arrangement and interconnection of the solar cells SZ in FIG. 9, but can also be used in modifications of this in order to avoid short circuits of the interconnected solar cells by isolating their edge regions from the contact strips.
- sealing material is applied to the first film web before the second film web on the flexible thin-film solar cells and on the first Film web, for example be applied by roll lamination.
- the dispenser assembly applies the sealing material as one or more strands or strips SP1, SP2 at the edge to the individual solar modules to be formed on the first film web, encompassing the flexible thin-film solar cells of a solar module. Suitable materials for the edge sealing butyl rubber or similar waterproof and vapor-tight plastic materials.
- a dispenser of the dispensing arrangement applies sealing material to the first film web in the region of a longitudinal edge of the first film web.
- Another dispenser of the dispenser assembly is movable transversely to the longitudinal edge of the first film web.
- this dispenser for sealing material can be moved at an acute angle to the conveying direction of the first film web and brings when moving in sealing material as two spaced strands SP3, SP4 on the first film web, which connect the two edge strands SP1 and SP2.
- the dispenser assembly applies the sealant material as one or more strands or stripes to the first film web at the edge of the individual solar modules to be formed.
- the sealant material is then applied by means of a roll laminator, preferably with temperature below the crosslinking temperature of the or one of the film webs or the sealant material on the web or one of the film webs attached.
- the flexible thin-film solar cells can also be so-called tandem or triple solar cells. These are multispectral solar cells, in which two layers of solar-receptive materials are superimposed, which absorb different areas of the light spectrum and thus achieve high efficiencies.
- the overhead, partially transparent solar cell allows light of specific wavelengths to pass through almost unhindered, so that it can be absorbed by the lower solar cell (s).
- Tandem solar cells are manufactured in thin-film technology in monolithic blocks, which can be combined, for example, with Fresnel lenses. In order to optimally absorb the different-wave photons in the individual layers, they are usually produced from different semiconductor materials.
- the top layer may be gallium arsenide and the bottom layer germanium.
- the gallium arsenide absorbs higher-energy radiation, but is permeable to significant proportions of low-energy radiation, which causes the germanium layer absorbed. But it is also a combination of different silicon qualities possible, for example, upper layer of amorphous silicon and the lower layer of microcrystalline silicon.
- the top layer may be gallium
- the middle layer may be indium arsenide
- the bottom layer may be gallium indium phosphide.
- the method and its variants or the device and its variants do not differ from the above-described single-layer solar cell methods / devices.
- a solar module with the following features to produce:
- a first, serving as a substrate film web carries a plurality of arranged on the first film web flexible thin-film solar cells, which with a first side rest on the first film web.
- Each of the flexible thin-film solar cells has an electric first pole and an electric second pole.
- a first flexible thin-film solar cell is arranged with at least its first pole in the vicinity of a second pole of a second flexible thin-film solar cell. Electrically conductive contact strips connect the first and the second poles of the flexible thin-film solar cells in the longitudinal and / or transverse direction to an edge of the first film web in series and / or in parallel with each other electrically.
- a transparent, flexible second thermoplastic film web is laminated to the first film web and the flexible thin film solar cells.
- a solar module is formed from the first and the second film web and the flexible thin-film solar cells located therebetween.
- the second film web is a thermoplastic film web.
- the flexible thin-film solar cells may have no adhesive layer on their photoelectrically inactive (lower) side, and an adhesive film may preferably be arranged between the first film web and the flexible thin-film solar cells, and a barrier film with adhesive layer may be applied as the second film web.
- Insulating material may be disposed between edge regions of the flexible thin film solar cells and the electrically conductive contact strips, and may include sealing material between the first film web and the second film web as one or more strands or stripes adjacent the individual solar modules to be formed surrounding the flexible thin film solar cells be.
- the perspective structure of the crosslinking station illustrated in FIG. 11 shows an input area and an output area for the flexible thin-film solar modules.
- it is a step-wise cross-linking station which is to be set by a suitable process control device to expose to it, not yet cross-linked solar module composites each a defined temperature profile, in which the film webs for the first time for the required period of time be brought into the range of the cross-linking temperature.
- the solar module composites pre-laminates
- the network station operates in the manner of a paternoster and promotes a solar module, for example, one step per minute at eg 15 stages through the cross-linking process.
- Fig. 12 illustrates a perspective schematic structure of a solar module with its different layers.
- FIG. 13 illustrates a schematic cross section through a solar module with a connection box mounted from the base layer.
- FIG. 14 shows a schematic cross section through a solar module, which otherwise corresponds to FIG. 13, with a connection box mounted from the barrier layer.
