Abstract
A stress dispersion type encapsulation structure of a concentrator cell module comprises a heat emission metal plate, a set of small silicon photovoltaic cell on the heat emission metal plate, a hot-melt adhesive layer covered on the set of small silicon photovoltaic cell and a piece of toughened glass covered on the hot-melt adhesive layer, wherein, the toughened glass covered on the hot-melt adhesive layer is composed a plurality of small toughened glasses, among which clearances are left. By adopting the utility model of concentrator cell module stress dispersion type encapsulation structure, the stress produced by flatulence and shrink can be dispersed, so that the hot-melt adhesive layer around the concentrator cell module can be prevented from being devoiced from the silicon photovoltaic cell, therefore, the long period stable generating of the solar energy generating concentrator cell can be ensured.
Description
Technical field
The utility model relates to a kind of solar power generation concentrator cell, relates in particular to a kind of stress decentralized encapsulating structure of concentrator cell module.
Background technology
The solar power generation concentrator cell is widely used in family and industrial and agricultural production, is a kind of real green energy resource.Now general with photocell as the device that luminous energy is changed into electric energy, by collector lens sunlight is pooled to and produces electric energy on the photocell.
The solar power generation concentrator cell generally comprises at least one concentrator cell module, typical concentrator cell module generally comprises heat-dissipating metal sheet, be installed in one group of little silicon photocell on the heat-dissipating metal sheet, cover one group on the little silicon photocell hot melt adhesive layer and cover toughened glass on the hot melt adhesive layer.In the concentrator cell module of prior art, heat-dissipating metal sheet and toughened glass are respectively a monoblock, this structure can produce a problem, be that the concentrator cell module will be worked under-40～85 ℃ environment, the wherein each parts phenomenon of all can expanding with heat and contract with cold, because the coefficient of expansion of heat-dissipating metal sheet and toughened glass differs greatly, sharply change in temperature and to produce when expanding with heat and contract with cold, will whole concentrator cell module be occured bending and deformation because of the coefficient of expansion is different, through after the flexural deformation repeatedly, the hot melt adhesive layer that is positioned at concentrator cell module periphery will break away from silicon photocell, cause air can enter silicon photocell, cause the rotten damage fully at last of corrosion of battery.This will have a strong impact on the generating efficiency of solar power generation concentrator cell.
The utility model content
The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of stress decentralized encapsulating structure of new concentrator cell module is provided.
The purpose of this utility model is achieved in that a kind of stress decentralized encapsulating structure of concentrator cell module, comprise heat-dissipating metal sheet, be installed in one group of little silicon photocell on the heat-dissipating metal sheet, cover one group on the little silicon photocell hot melt adhesive layer and cover toughened glass layer on the hot melt adhesive layer, be characterized in that described toughened glass layer is combined by the little toughened glass of polylith.
Leave the gap between the little toughened glass of described each piece.
Link to each other by PUR between the little toughened glass of described each piece.
Described toughened glass layer is combined by 6 blocks of little toughened glass, and 6 blocks of little toughened glass are formed 2 * 3 arrays.
Described toughened glass layer is combined by 9 blocks of little toughened glass, and 9 blocks of little toughened glass are formed 3 * 3 arrays.
Described toughened glass layer is combined by 8 blocks of little toughened glass, and 8 blocks of little toughened glass are formed 2 * 4 arrays.
Adopt the stress decentralized encapsulating structure of the utility model concentrator cell module; the stress that produces owing to expanding with heat and contract with cold is disperseed; the hot melt adhesive layer of protection concentrator cell module periphery can not break away from silicon photocell, thereby guarantees that the solar power generation concentrator cell can the long period stable electric generation.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the stress decentralized encapsulating structure of the utility model concentrator cell module.
Embodiment
Cooperation is referring to Fig. 1, the stress decentralized encapsulating structure of the utility model concentrator cell module, comprise heat-dissipating metal sheet 1, be installed in one group little silicon photocell 2 on the heat-dissipating metal sheet, cover one group little on the silicon photocell 2 hot melt adhesive layer 3 and cover toughened glass layer 4 on the hot melt adhesive layer 3, toughened glass layer 4 is wherein combined by the little toughened glass of polylith, leave gap 41 between the little toughened glass of each piece, or link to each other by PUR.
The stress decentralized encapsulating structure of the utility model concentrator cell module can adopt 6 blocks of little toughened glass to form 2 * 3 arrays and cover on the hot melt adhesive layer; Also can adopt 9 blocks of little toughened glass to form 3 * 3 arrays covers on the hot melt adhesive layer; Can also adopt 8 blocks of little toughened glass to form 2 * 4 arrays covers on the hot melt adhesive layer.It can also be the combination array of other form.
