Definitions
- the present invention relates to a method for the production of solar modules, in which air pockets are avoided.
- Solar modules are components for direct generation of electricity from sunlight. Key factors for a cost-efficient generation of solar power are the efficiency of the solar cells used, as well as the manufacturing costs and the durability of the solar modules.
- a solar module usually consists of a framed composite of glass, interconnected solar cells, an embedding material and a backside construction.
- the individual layers of the solar module have to fulfill the following functions.
- the front glass protects against mechanical and weather influences. It must have the highest transparency in order to minimize absorption losses in the optical spectral range of 300 nm to 1150 nm and thus efficiency losses of the silicon solar cells usually used for power generation. Normally, hardened, low-iron white glass (3 or 4 mm thick) is used whose transmittance in the above spectral range is 90 to 92%. Furthermore, the glass provides a significant contribution to the rigidity of the module.
- the embedding material (usually EVA (ethyl vinyl acetate) films) serves to bond the entire module assembly. EVA melts during a lamination process at about 150 ° C, flows into the interstices of the soldered solar cells and crosslinked by a thermally initiated chemical reaction. A formation of air bubbles, which lead to reflection losses, is avoided by a lamination under vacuum.
- EVA ethyl vinyl acetate
- the back of the module protects the solar cells and the embedding material from moisture and oxygen. In addition, it serves as a mechanical protection against scratching, etc. when mounting the solar modules and as electrical insulation.
- another glass or a composite foil can be used.
- PVF polyvinyl fluoride
- PET polyethylene terephthalate
- PVF aluminum PVF are used.
- the encapsulating materials used in the back of the solar module construction must in particular have good barrier properties against water vapor and oxygen. Water vapor or oxygen does not attack the solar cells themselves, but causes corrosion of the metal contacts and chemical degradation of the EVA embedding material. A destroyed solar cell contact leads to a complete failure of the module, since normally all the solar cells are electrically connected in series in a module. Degradation of the EVA is indicated by yellowing of the module, associated with a corresponding reduction in power through light absorption and visual deterioration.
- solar modules In order to achieve competitive electricity generation costs of solar power despite the relatively high investment costs, solar modules have to achieve long operating times. Today's solar modules are therefore designed for a service life of 20 to 30 years. In addition to high weather stability The temperature requirements of the modules are very demanding, and their temperature during operation can vary cyclically between 80 ° C in full sunlight and temperatures below the freezing point. Accordingly, solar modules will undergo extensive stability testing (N o rm tests na ch I EC 61 2 15 and I EC 61730), which will include weathering tests (UV irradiation, damp heat, temperature cycling) as well as hail impact tests and electrical insulation tests.
- US Pat. No. 4,830,038 and US Pat. No. 5,008,062 describe the attachment of a plastic frame around the relevant solar module, which is obtained by the RIM process (Reaction Injection Molding).
- the polymeric material used is an elastomeric polyurethane.
- Said polyurethane should preferably have an E modulus in a range of 200 to 10,000 psi (corresponding to about 1.4 to 69.0 N / mm 2 ).
- reinforcing members of, for example, a polymeric material, steel, or aluminum may be incorporated into the frame when formed.
- fillers can be incorporated into the frame material. These may be, for example, platelet-type fillers such as the mineral wollastonite or needle-like / fibrous fillers such as glass fibers.
- DE 37 37 183 A1 also describes a method for producing the plastic frame of a solar module, wherein the Shore hardness of the reinforced part of the frame is selected such that a sufficient rigidity of the frame and a thickness are achieved elastic absorption of the solar generator is ensured.
- the modules described above are erected by means of stand constructions or, for example, mounted on roof structures. You need a certain modulus rigidity, which is adversely affected by a (plastic) frame and the relatively heavy, approx. 3 to 4 mm thick windscreen results. In addition, the front screen already has a certain absorption due to its thickness, which in turn adversely affects the efficiency of the solar module.
- Foil modules are the embedding of solar cells between two plastic films, if appropriate also between a front-side, translucent film and a flexible metal sheet (aluminum or stainless steel) on the rear side.
- a metal sheet aluminum or stainless steel
- "UNIsolar ®” brand laminates consist of thin, thin-film silicon vapor deposited on thin stainless steel sheet sandwiched between two plastic sheets, which must then be adhered to a rigid support structure such as sheet metal roof shells or metal sandwich panels
- DE 10 2005 032 716 A1 describes a flexible solar module 11 which has to be applied axially on a rigid support structure 11.
- the disadvantage here is the additional working step, the subsequent bonding with a supporting structure.
- US 2003/0178056 A1 discloses a solar module which has a first and a second protective layer, wherein the solar cells are sealed between these two layers. Between the second, waterproof layer and the solar cells is an insulating film, which consists of a plastic.
- the second, waterproof protective layer comprises films, which include a metal foil.
- the metal foil used here is an aluminum, iron or zinc foil.
- a weatherproof film for sealing a photovoltaic module is also known from DE 102 31 401 AI.
- the weatherproof layer is made up of a plurality of polymer layers, wherein here additionally a moisture-proof layer of aluminum, galvanized steel, silicon oxide, titanium oxide or zirconium dioxide is present between the polymer layers.
- a corresponding photovoltaic module is produced in layered construction.
- EP 1 302988 A2 describes a photovoltaic module and a method for its production.
- a special adhesive layer is described, which consists of an aliphatic thermoplastic polyurethane.
- the solar elements are embedded.
- the solar module includes a cover plate and a backsheet.
- One possible manufacturing process here is lamination with the aid of a roll laminator.
- a laminate of a cover plate or film and an adhesive film is produced in a roll laminator.
- a composite of cover with adhesive film; Solar strings; Composite of back and adhesive film introduced one above the other.
- the 3 individual components are joined together. This requires the exact alignment of the 3 components to each other.
- the solar module has a rear side made of a sandwich element.
- a sandwich element comprises a core layer and outer layers applied thereto.
- the Outer layers of fiber-reinforced plastic give the element a high rigidity.
- the sandwich element has a low weight.
- the solar module should have as low as possible a basis weight and at the same time be as rigid as possible, so that it does not require only one simple support or fixing structure and it is necessary easy to handle. Furthermore, the solar module should have sufficient composite long-term stability to prevent delamination and / or moisture from entering.
- the object is achieved by a method according to the invention.
- the invention therefore provides a method for producing a solar module (10) comprising a sandwich element (6), one or more solar elements (3) embedded in an adhesive layer (2) and a transparent layer (1) facing a light source in operation characterized in that in a first step a first composite (7) comprises a sandwich element (6) comprising at least one core layer (5) and at least one outer layer (4) located on each side of the core layer (5), and an adhesive layer (2b ) will be produced,
- a second composite (8) is produced, which has the transparent layer (1), an adhesive layer (2a) and at least one solar element (3) and
- the composites from the first and the second step are connected to one another via the respective adhesive surfaces.
- a second composite (8) is produced, which is the at least one solar element (3) which is connected via an adhesive layer (2a) with one in operation of the light source facing transparent layer (1), that when bringing together no air is trapped in the final product over the adherends of the two composites.
- a sandwich element (6) via the adhesive layer (2b) is not flat on a composite (8) of transparent layer (1), Solar element (3) and adhesive layer (2a) is placed.
- the two adhesive layers (2a) and (2b) may consist of the same or of different materials.
- the composites (7) and (8) are optionally connected to one another under the influence of temperature and / or optionally under the application of a vacuum.
- a method according to the invention thus makes it possible to produce a solar module (10) according to FIG. 1, which has a sufficiently high stability due to the sufficiently high bending strength of the sandwich element (6). Due to this sufficiently high rigidity, the solar module (10) is easy to handle and does not bend even after a long time.
- the composite long-term stability of such a composite is also very good, since the difference between the coefficient of thermal expansion of the sandwich element (6) is very small compared to that of the transparent layer (1) and that of the solar cells. Therefore, mechanical stresses hardly occur and the risk of delamination is very low.
