Description

A kind of photovoltaic battery panel of anti-steam
Technical field
The utility model is related to solar cell package technical field, and in particular to a kind of photovoltaic battery panel of anti-steam.
Background technology
Solar energy is a kind of clean reproducible new energy, is increasingly favored by people, in people's life, work Play an important role.Thus generated electricity and obtained in municipal administration, household, office, traffic and the occasion such as portable using solar photovoltaic assembly To being widely applied.Photovoltaic module can be laid at the top of all kinds of small and medium construction things, received solar power generation and used for interior, Also street, highway and tourist recreation place can be arranged on, for outdoor lighting and cities and towns brightening, husky film or spaciousness can be also laid on Area sets up hair system grid connection and realizes that electric energy is exported.
Solar photovoltaic assembly (solar panel) is to combine equipped by cell piece, glass plate, EVA film and back plate seals The plate shaped unimorph formed in frame, this plate shaped unimorph can be utilized directly, can also be used monomer is combined and spliced again.Straight Connect makes that side infiltration of the steam from plate shaped unimorph need to be solved using plate shaped unimorph, is also had when being spliced into large-scale tabular a small amount of Steam is penetrated between each plate shaped unimorph through splicing gap.In order to solve side infiltration problem of the steam from photovoltaic module, The problem of influenceing photovoltaic module generating efficiency and service life, photovoltaic module can be influenceed generation efficiency to decay by steam etc..Respectively Individual monomer need to carry out effective waterproof impervious processing when manufacturing.It is provided with two surfaces up and down of cell piece resistance to The EVA film of aqueous material, then carry out encapsulation process in the surrounding of cell piece.More than now current photovoltaic battery panel using directly pressure with Mode, photovoltaic battery panel each side do not carry out effective waterproof gas disposal.The problem of this mode is primarily present is water Vapour easily penetrates into from side, using seal failure after certain time, the decay of photovoltaic cell plate efficiency can be caused to influence electric energy Conversion ratio.Therefore, a kind of new encapsulation water vapor proofing structure of urgent demand penetrates into cell piece to completely cut off steam.
Utility model content
For defect of the prior art, the utility model provides a kind of photovoltaic battery panel of anti-steam, the letter of its structure It is single, easily manufactured and with low cost and with good anti-steam effect.
The technical solution of the utility model is:A kind of photovoltaic battery panel of anti-steam, including backboard, cover layer and be used for The cell piece group of electric energy is converted light energy into, the cover layer is set in parallel on backboard and shape between cover layer and backboard Into an accommodating layer, cell piece is mounted in the accommodating layer, is additionally provided with the accommodating layer for preventing steam from entering accommodating layer Butyl rubber belt group.
Further, in order that being not directly contacted between backboard and cell piece group and between cover layer and cell piece group, Isolated to reach the purpose of more preferable anti-aqueous vapor, medial surface and the cell piece group of the backboard and cover layer using EVA film Between using EVA film isolate, the butyl rubber belt group along EVA film outer contour distribution.
Further, the butyl rubber belt group include along EVA film two long side arrange two vertical butyl rubber belts with The two horizontal butyl rubber belts arranged along two short sides of EVA film, and vertical butyl rubber belt and transverse direction butyl rubber belt respectively with Backboard is connected with the medial surface bonding of cover layer.
Further, the vertical butyl rubber belt and horizontal butyl rubber belt join end to end to form a rectangle frame, institute successively Cell piece group is stated in rectangle frame.
Further, the cell piece group includes the multiple cell pieces being uniformly distributed in rectangle frame.
Further, in order that butyl rubber belt group can effectively contact preceding sealer and backboard and complete effective bonding Connection, the thickness of the butyl rubber belt group is not less than the thickness of cell piece.
Further, in order to enable cell piece group to receive effective luminous energy, the cover layer and EVA film are Hyaline membrane.
Compared with the existing technology, the beneficial effects of the utility model are:
1st, simple in construction, convenient processing and manufacture and cost is low can be widely used in photovoltaic battery panel anti-steam technology neck Domain;
2nd, the butyl rubber that water vapor transmittance is only 0.03g/ ㎡ d is enclosed in the edge laminating packaging one of photovoltaic battery panel Band, is avoided that steam penetrates into from the side of photovoltaic battery panel, can effectively completely cut off the extraneous medium with photovoltaic cell intralamellar part and hand over Change, and then can effectively slow down photovoltaic battery panel efficiency decay in use, improve the service life of photovoltaic battery panel, Reduce the use cost of photovoltaic battery panel.
