Abstract
The invention relates to a double-glass-layer photovoltaic module which comprises a monocrystalline silicon cell, a rear panel glass layer and a toughened glass layer. A first PVB (polyvinyl butyral) rubber film layer is adhered on the upper surface of the monocrystalline silicon cell, an ultrathin highly-transparent rear panel layer is arranged on the first PVB rubber film layer, an EVA (ethylene-vinyl acetate) rubber film layer is arranged on the ultrathin highly-transparent rear panel layer, the rear panel glass layer covers the EVA rubber film layer, a second PVB rubber film layer is adhered on the lower surface of the monocrystalline silicon cell, and the toughened glass layer covers the second PVB rubber film layer. The EVA rubber film layer is sandwiched between the rear panel glass layer and the monocrystalline silicon cell, so that adhesive force, durability and optical characteristics can be effectively improved, and the double-glass-layer photovoltaic module is reasonable in design structure and high in light use efficiency.
Description
Technical field
The present invention relates to field of solar cells, especially a kind of pair of glass photovoltaic module.
Background technology
Development along with world industry; Resources such as oil, natural gas, coal are in day by day exhaustion; Human thinking to resource makes solar utilization technique obtain very big development; At present world's photovoltaic industry is with 31.2% annual average rate of increase high speed development, and it is the first to be positioned at global energy GENERATION MARKET growth rate.In recent years, along with the fast development of photovoltaic industry, monocrystalline silicon was used to manufacturing solar cells, demonstrated the situation that supply falls short of demand.Solar panel is under solar radiation, and luminous energy just changes into electric energy immediately, and can ceaselessly generate electricity, can continuous operation more than 20 years.The direct current that he sends can directly be supplied with electrical appliance, can also be stored in the storage battery, and another mistake becomes the 220V/380V alternating current; And then be assembled into the solar power generation unit; Supply various household electrical appliance to use, can also many silion cells be linked, be assembled into photovoltaic plant and transmit electricity to national grid.Solar-energy photo-voltaic cell is that country widelys popularize, and development prospect is bright, does not have the green energy resource that pollutes.
At present in fields such as building, traffic the most frequently used to be pair glass photovoltaic modulies; Two glass photovoltaic modulies are made up of upper and lower two sheet glass and the solar battery sheet composite bed that is arranged between two sheet glass; The two glass photovoltaic modulies of this kind can combine with building as photovoltaic curtain wall; As the external part of going along with sb. to guard him of building or as the present top board and the side plate of pandemic electric four-wheel vehicle on the market, and can also can play the purpose of generating as the part of building or car body.
Above-mentioned two glass photovoltaic modulies, it exists glassy layer and solar battery sheet degree of adhesion poor, and light utilization efficiency is low, optical characteristics, shock-resistant ability, useful life are short.
Summary of the invention
The technical problem that the present invention will solve is: in order to overcome the above-mentioned middle problem that exists, a kind of pair of glass photovoltaic module is provided, the strong and long service life of reasonable, the shock-resistant ability of its project organization.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pair of glass photovoltaic module comprises the monocrystalline silicon battery sheet, is located at the back-panel glass layer of monocrystalline silicon battery sheet top and is located at the toughened glass layer of monocrystalline silicon battery sheet below that described monocrystalline silicon battery sheet upper surface is pasted with a PVB adhesive film; The one PVB adhesive film is provided with backsheet layer; Backsheet layer can be selected the bleed-through flaggy of ultra-thin height for use, and backsheet layer is provided with the EVA adhesive film, and the EVA glued membrane has the high grade of transparency, be prone to store, compare PVB has stronger soundproof effect; Low melting point; Be prone to flow, can be applicable to the doubling technology of various glass, the back-panel glass layer covers on the EVA adhesive film; Described monocrystalline silicon battery sheet lower surface is pasted with the 2nd PVB adhesive film, and the toughened glass layer covers on the 2nd PVB adhesive film.
Described toughened glass layer is low steel wool face toughened glass layer, and low steel wool face toughened glass is that iron content is lower, glass touch perception villous, approach the equally hard glass of steel.
The invention has the beneficial effects as follows: described pair of glass photovoltaic module, folder is established the EVA glued membrane between back-panel glass and monocrystalline silicon battery sheet, can improve adhesion strength, durability, optical characteristics effectively, and its project organization is reasonable and light utilization efficiency is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the overall structure sketch map of of the present invention pair of glass photovoltaic module.
Accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1, monocrystalline silicon battery sheet, 2, the back-panel glass layer, 3, the toughened glass layer, the 4, the one PVB adhesive film, 5, backsheet layer, 6, the EVA adhesive film, the 7, the 2nd PVB adhesive film.
Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Two glass photovoltaic modulies as shown in Figure 1; Comprise monocrystalline silicon battery sheet 1, on monocrystalline silicon battery sheet 1 upper surface, be pasted with a PVB adhesive film 4, the one PVB adhesive films 4 and be provided with backsheet layer 5; Backsheet layer 5 is provided with EVA adhesive film 6; Back-panel glass layer 2 covers on the EVA adhesive film 6, is pasted with the 2nd PVB adhesive film 7 on monocrystalline silicon battery sheet 1 lower surface, and toughened glass layer 3 covers on the 2nd PVB adhesive film 7.
Of the present invention pair of glass photovoltaic module; EVA adhesive film 6 and backsheet layer 5 on the basis that has the PVB glued membrane between back-panel glass layer 2 and the monocrystalline silicon battery sheet 1, have been increased again; In use; EVA adhesive film 6 can make back-panel glass layer 2 and backsheet layer 5 more bonding, improves light transmittance, strengthens light utilization efficiency.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
