Description
Technical field
The present invention relates to solar module, relate in particular to a kind of BIPV and use solar module.
Background technology
The greenhouse gas emission of high buildings and large mansions is serious day by day, is one of reason that causes climate warming.Using green energy resource to substitute traditional energy is one of important means that reduces greenhouse gas emission, wherein, and the tool of solar energy power generating development prospect.Solar module is combined with the top or the exterior wall of building; To building electric energy is provided, not only can realizes original place generating, original place use, practice thrift the investment of electrical network and the energy consumption of minimizing conveying circuit; Reach the purpose of energy-saving and emission-reduction, and do not need the land occupation resource.Therefore become one of focus of new forms of energy development.
The ordinary construction of existing BIPV solar module is: with the surface layer glass of low iron glass as solar battery chip; With the backboard of simple glass as solar battery chip; Through two-layer hot melt adhesive film solar battery chip is clipped between surface layer glass and the back-panel glass, makes through the lamination encapsulation.There is following defective in the BIPV solar module of this employing double glazing encapsulation: 1. weight is big, in the building walls difficult installation.2. be prone to brokenly, possibly fall after cracked and hurt sb.'s feelings.3. photoelectric conversion efficiency is low.4. radiating effect is poor.
Summary of the invention
The object of the present invention is to provide a kind of BIPV to use solar module, this BIPV is not only in light weight with solar module, impact resistance, and photoelectric conversion efficiency is high, and good heat dissipation effect.
For reaching above-mentioned purpose; Solar module is used in BIPV of the present invention; The backboard and the surface layer glass that comprise solar battery chip and be arranged at its both sides; Wherein, Said backboard is for have the aluminium sheet or the aluminium alloy plate of reflector layer at least on a surface, said reflector layer and said solar battery chip are relatively and in the latticed insulating cell that printing opacity is set between them, said backboard and said insulating cell, said insulating cell and said solar battery chip, said solar battery chip and said surface layer glass are all through weather-proof hot melt adhesive film bonding.
In a kind of preferred version, said backboard is for having the aluminium sheet or the aluminium alloy plate of reflector layer, remaining surface process anodized on a surface.
Said solar battery chip can adopt the crystal silicon solar energy battery chip, like the monocrystaline silicon solar cell chip, and the polysilicon solar cell chip.Said solar battery chip also can adopt the amorphous silicon thin-film solar cell chip, or the microcrystalline silicon solar cell chip.Said solar battery chip can also adopt multi-element compounds thin-film solar cells chip, like copper-indium-galliun-selenium film solar cell chip, cadmium telluride diaphragm solar battery chip etc.
The thickness of backboard can confirm that preferable range is 2～5mm according to the size of solar module.
The present invention also provides the backboard of a kind of BIPV with solar module, and this backboard is for have the aluminium sheet or the aluminium alloy plate of reflector layer at least on a surface.
In a kind of preferred version, backboard is for having the aluminium sheet or the aluminium alloy plate of reflector layer, remaining surface process anodized on a surface.
The present invention also provides a kind of method that improves BIPV with solar module photoelectric conversion efficiency, weather resistance, impact resistance performance and radiating effect simultaneously; Be specially: adopt to have the aluminium sheet of reflector layer or the backboard that aluminium alloy plate is done said solar module at least on a surface; On said aluminium sheet or aluminium alloy plate, there is not the surface of reflector layer to carry out anodized; During assembling, the solar battery chip that makes said reflector layer and said solar module is relatively and in the latticed insulating cell that printing opacity is set between them.
Because backboard adopts aluminium matter backboard; Make this BIPV be able to alleviate greatly with the weight of solar module; And it is not easily broken when bumping; Even skin glass is chipping, solar module can not fall yet and hurt sb.'s feelings, and is convenient to very much install at building walls and top.Because aluminium matter backboard is provided with reflector layer, can be with the sunlight that sees through solar battery chip with on irreflexive mode reflected back solar battery chip, this has not only improved photoelectric conversion efficiency, and building is had heat-blocking action.Simultaneously, because the heat conductivility of aluminium matter backboard is superior, help the heat radiation of solar battery chip, this has further improved the photoelectric conversion efficiency of this solar module.
In addition, this BIPV has good weather resistance with solar module.
