Description
Technical field
What the present invention relates to is a kind of photovoltaic field, especially a kind of solar cell two-layer compound device.
Background technology
In the prior art, known technology is that BIPV is an important application of thin-film solar cells, it is the function in conjunction with solar cell power generation and skin, on building, make it play the double duty that not only can generate electricity but also can replace construction material in the solar module device.In the area of land price costliness, BIPV is to solve the preferred plan that cost of land is too high and the integration generating is transported.Building had been brought into use thin-film solar cells already, because it can generate electricity, can reduce again the discharge capacity of carbon dioxide, and this is following new trend.In this respect, thin-film solar cells has unlimited potentiality.The difference of Yian holding position, BIPV has number of different types, as being combined with the roof, being combined with exterior wall, be combined with solar protection devices, doing that glass curtain wall is used etc.BIPV has following advantage: 1. the building materials such as saving solar cell supporting construction, and alternative roof, metope, window; 2. save the solar cell installation cost; 3. effectively utilize the surface area of building, do not need other land occupation; 4. can sunshade, reduce the building appearance temperature; 5. increase building attractive in appearance; 6. with solar energy and building combination, make building that the power supply supply of oneself can be arranged.
Along with the energy in national economy strategic position improve constantly and to the development of solar utilization technique, BIPV has obtained rapidly development. as a kind of important installation form of BIPV, photovoltaic curtain wall combines photovoltaic module and building, has realized the several functions such as the generating, daylighting of building maintenance structure, heat insulation, insulation and sound insulation.Yet, the photovoltaic curtain wall modular construction that uses at present is solar photovoltaic interlining glass, be solar energy glass-EVA(ethylene-vinyl acetate copolymer) film or PVB(polyvinyl butyral resin) film-glass basal plate structure, or solar photovoltaic hollow glass, be solar energy glass-EVA(ethylene-vinyl acetate copolymer) film or PVB(polyvinyl butyral resin) film-double glazing (glass+air layer+glass), assembled conductor again, terminal box, the photovoltaic curtain wall of this structure is common solar sandwich photovoltaic module or two glass solar photovoltaic assembly on the one hand, insulation and defening effect are relatively poor, can not satisfy high energy-saving design building to the requirement of photovoltaic curtain wall insulation and sound insulation property; Adopt in addition independently solar battery sheet, so that the technical process more complicated.Perhaps hollow-vacuum, hollow-vacuum-sandwich composite, although solved to a certain extent the problem of insulation and sound insulation, but because adopted the glass structure more than 3 layers, cause the complex manufacturing process of assembly, bad realization and control, and cause the assembly manufacturing cost higher, therefore the problem such as assembly weight is larger exists certain problem in practice.Upper glass sheet directly contacts with atmosphere in the present solar photovoltaic interlining glass in addition, airborne pollutant after a period of time, and such as dust, grease etc. can be attached on glass, cause the glass light transmittance to descend.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of solar cell two-layer compound device, make it have lower thermal transmission coefficient and higher sound insulation property, temperature stabilization and peace and quiet in the holding chamber, to improve energy-saving effect and the residence comfort of photovoltaic curtain wall, simultaneously can play the generating effect again, by electric energy storage or saving equipment, the electrical power storage that solar cell produces is got up, required electric energy can be provided to a great extent.
This programme is achieved by the following technical measures: a kind of solar cell two-layer compound device includes glass sheet, lower glass sheet and solar cell; Solar cell is arranged on lower glass sheet internal layer, and by lower plate glass edge section extraction electrode; Upper glass sheet and lower glass sheet form an airtight cavity.
Preferred as this programme: cavity can be vacuum chamber or cavity; Can be filled with dry air or inert gas in the cavity.
Preferred as this programme: scribble self-cleaning coating on the skin of upper glass sheet, comprise TiO
2, SnO
2, super-hydrophobic type organic, super hydrophilic type organic.
Preferred as this programme: solar cell sticks on lower glass sheet internal layer by film.
Preferred as this programme: film adopts ethylene-vinyl acetate copolymer film or polyvinyl butyral resin film.
Preferred as this programme: solar panel directly is produced on lower glass sheet internal layer by by the hull cell manufacture craft.
Preferred as this programme: the thickness of cavity is 0.1mm-20mm.
Preferred as this programme: solar cell can be one or more pieces, the in parallel or use that is cascaded by intercell connector.
The beneficial effect of this programme can learn according to the narration to such scheme, because the structure that glass sheet and lower glass sheet and solar cell are combined in this scheme can be stored assembly by integrated a kind of electric energy; Double-layer glass structure not only can provide ultralow thermal transmission coefficient and higher sound insulation property, can also be so that the assembly manufacturing process, and weight and cost aspect are more easily used; Solar cell and the double glazing of novel thin film structure merge fully, and a kind of construction package of brand-new green, energy-saving building or other usefulness is provided.This solar energy cladding glass can be used as the building-material-type photovoltaic module and is applied to building curtain wall, also can be used for photovoltaic roof, photovoltaic window etc., can effectively reduce building energy consumption, improves energy-saving effect and the residence comfort of building.Automatic cleaning coating can make upper plate glass can keep for a long time high transmission rate.
This shows, the present invention compared with prior art, heat transfer efficiency is higher, technique is easier, range of application is wider, has outstanding substantive distinguishing features and progressive significantly, the beneficial effect of its enforcement also is apparent.
