Description
Technical field
The utility model belongs to area of solar cell, and in particular to a kind of solar photovoltaic assembly.
Background technology
With society and economic rapid development, the energy needs increasingly to increase, fossil energy increasingly exhausted and to life
Pollution caused by state environment, serious threat society and economic sustainable development.Therefore, there is an urgent need to use regenerative resource
It is substituted.Solar energy is worldwide obtained as a kind of inexhaustible green regenerative energy sources
Extensive concern.
The solar cell module of the prior art generally comprises glass cover-plate, solar battery sheet and backboard, more than each layer
Between bonded through EVA adhesive film, have the following problems mostly：1. traditional solar components are with photovoltaic glass effective transmittance
92% or so, about 8% visible ray is due to glass-reflected and absorption loss water；2. in the long-term use, glass surface can accumulate
Tired certain dust, seriously affects the light transmittance of glass, and then influences entire photoelectric conversion efficiency；3. photovoltaic panel is more crisp
It is weak, it is easily damaged during transportational process or use, service life is short.
Utility model content
In view of the deficienciess of the prior art, the utility model offer effectively improves intensity, light transmittance height and has from clear
The solar photovoltaic assembly of clean function.
The utility model is achieved through the following technical solutions：
A kind of solar photovoltaic assembly, including solar cell layer, the upper surface of the solar cell layer is equipped with steel
Change glassy layer, polycarbonate layer, the toughened glass layer are provided between the solar cell layer and toughened glass layer
Surface coated with self-cleaning film layer, anti-reflection film layer, the sun are provided between the toughened glass layer and self-cleaning film layer
The lower surface of energy battery layers sets only backboard.
Further, EVA film layer is provided between the solar cell layer and polycarbonate layer.
Further, the self-cleaning film layer uses TiO2Film layer, the anti-reflection film layer use SiO2Or Si3N4Film layer.
Further, the toughened glass layer uses ultrawhite toughened glass layer.
Compared with prior art, the beneficial effects of the utility model are：
1st, the surface of the utility model toughened glass layer is coated with anti-reflection film layer, can increase the effective transmittance of glass
2.5%-3%, improves effective transmissivity of sunlight, and then is effectively increased the photoelectric conversion efficiency of solar photovoltaic assembly；
2nd, the surface of the utility model toughened glass layer is coated with TiO2Self-cleaning film layer, with flexible hydrophily and
Photocatalysis characteristic can achieve the purpose that self-cleaning, the impurity such as the dust that tempered glass surface is adhered to effectively be reduced, so as to carry
The transmitance of high solar light；
3rd, polycarbonate layer is provided between the utility model solar cell layer and toughened glass layer, can effectively be increased
The compression strength of strong tempered glass improves the intensity of solar photovoltaic assembly, extends its service life, reduces use cost.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In attached drawing：1. solar cell layer；2. polycarbonate layer；3. toughened glass layer；4. anti-reflection film layer；It is 5. self-cleaning
Net film layer；6.EVA film layers；7. backboard.
Specific embodiment
A kind of solar photovoltaic assembly as shown in Figure 1, including solar cell layer 1, the upper surface of solar cell layer 1
Toughened glass layer 3 is installed, polycarbonate layer 2, tempering glass are provided between solar cell layer 1 and toughened glass layer 3
The surface of glass layer 3 is coated with self-cleaning film layer 5, and anti-reflection film layer 4, the sun are provided between toughened glass layer 3 and self-cleaning film layer 5
The lower surface of energy battery layers 1 sets only backboard 7.
Further, EVA film layer 6 is provided between solar cell layer 1 and polycarbonate layer 2.
Further, self-cleaning film layer 5 uses TiO2Film layer, anti-reflection film layer 4 use SiO2Or Si3N4Film layer.
Further, toughened glass layer 3 uses ultrawhite toughened glass layer.
In conclusion the only preferred embodiment of the utility model, is not used for limiting the utility model implementation
Scope, the equivalent change carried out by all shapes according to described in the utility model claims scope, construction, feature and spirit is with repairing
Decorations, should all be included in the right of the utility model.
