Description
Technical field
The present invention relates to solar cell package technical field, can effectively stop that steam enters encapsulation more particularly, to one kind
Solar cell in double glass photovoltaic modulies.
Background technology
In recent years, photovoltaic industry is quickly grown in China, the research of photovoltaic component encapsulating raw material and
Exploitation is also more and more deep.Double glass photovoltaic modulies instead of backboard using low thickness semi-tempered glass, and due to eliminating backboard
Use, steam can only be by component perimetric penetration, therefore the integrity problem of component is accordingly reduced, for wet environment and
The adverse circumstances such as ultraviolet, sand, alkali, acid, salt fog, double glass photovoltaic modulies all show stronger resistance.In addition, double glass photovoltaics
Installation aluminum alloy frame can not had to after component edge sealing, and be directly mounted on photovoltaic system, so as to greatly reduce group
Part manufacturing cost.
But solar double-glass assemblies still have two insoluble problems at present.On the one hand it is upper and lower two in lamination process
Sheet glass is easily shifted over, and causes to produce bad；On the other hand it is that no good method prevents surrounding steam from penetrating into, influences
Component generating efficiency and reliability.
The content of the invention
In view of this, it is an object of the invention to provide a kind of more excellent double glass photovoltaic modulies, to solve asking for prior art
Topic.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of double glass photovoltaic modulies, include cover-plate glass, upper packaging adhesive film, solar cell layer, lower encapsulation successively from top to bottom

Shape raised line, the cover-plate glass are provided with described in the n+1 circles being looped around from inside to outside on the outside of the surrounding of the solar cell layer
Upper ring rib, n+1 encloses the upper ring rib and is spaced to form the corresponding n rings for accommodating the lower ring rib between any two
Shape pit；N is the natural number more than 0.
In certain embodiments, as being provided around in one of them of the cover-plate glass and the back-panel glass in institute
State the ring rib described in the multi-turn on the outside of the surrounding of solar cell layer, the cover-plate glass and the back-panel glass it is another
It is individual to be provided with identical with the ring rib quantity and correspond the annular groove being engaged with the ring rib described in multi-turn.
Staggered the structure of occlusion using this plurality of ring rib up and down, steam can be better protected from and entered from surrounding,
Also lamination process middle cover glass sheet and the shifting phenomena of back-panel glass are preferably avoided.
As a preferable aspect, the cover-plate glass is respectively equipped with the both sides of long side along the solar cell layer
The extension of one pair of which side bulge-structure, the back-panel glass is respectively equipped with the both sides of short side along the solar cell
The bulge-structure of another opposite side extension of layer；Or
The cover-plate glass is respectively equipped with the both sides of short side along the convex of the one pair of which side extension of the solar cell layer
Structure is played, the back-panel glass is respectively equipped with the both sides of long side along the convex of another opposite side extension of the solar cell layer
Play structure.
After such design, it is combined into after the bulge-structure lamination on the bulge-structure and back-panel glass of cover-plate glass
One complete annular protrusion, solar cell layer is surrounded wherein, and also avoid cover-plate glass and exist with back-panel glass
Displacement in lamination process.
As another preferable aspect, the cover-plate glass is respectively equipped with the both sides of long side along the solar cell
The bulge-structure of the one pair of which side extension of layer, the back-panel glass are respectively equipped with the both sides of short side along the solar-electricity
