Description
Technical field
Sealed the present invention relates to sealant used for solar batteries, the solar cell module comprising its cured layer and with it
The method of solar cell module.
Background technology
At present, it is of increasing concern as the solar cell in energy source using solar radiation.To produce high voltage and exempting from
It is affected by, generally use sealant is by the multi-disc solar cell sealing of electrical connection in smooth surface protective layer and the back of the body
So that solar cell module is made between smooth surface protective layer.Conventional sealant used for solar batteries is mainly EVA class sealants
With two kinds of organic silicon sealant.Wherein, organic silicon sealant is because it is not in that EVA class sealants produce in hygrothermal environment
Raw acetic acid and the problem of cause electrode of solar battery to corrode, thus obtained in solar cell sealing field more extensive
Using.
JP2013-112719A, CN102276989A, CN102892837A individually disclose a kind of used for solar batteries close
Seal agent.Although these sealants can show good cohesive to solar cell module back veneer, these sealants exist
During for the external environment condition of ultraviolet radiation such as sunshine be present, the bonding that solar cell module can not be maintained a long-term stability
Property.Sealant disclosed in especially CN102276989A, because its used organopolysiloxane contains a large amount of phenyl, when
It is also easy to that xanthochromia occurs when being chronically at sunshine environment, influences the outward appearance of sealant.Moreover, above-mentioned document does not refer to that its is close yet
The vapor permeability and oxygen permeability of agent are sealed, thus can not learn that can these sealants be prevented because of moisture and oxygen infiltration
Caused solar cell failure problem.
CN103525094A discloses the photovoltaic module organosilicon group for encapsulation of photovoltaic cells (i.e. solar cell)
Compound, there is at least 80g/m under 40 DEG C and 1mm thickness after its is cured2It vapor permeability.But document institute

The linear organopolysiloxane of sub- norbornane based structures, straight chain type organic hydrogen of (B) main chain containing sub- norbornane based structures
Polysiloxanes.Although its cured product of the silicon composition has good ultra-violet resistance and moisture-proof, its bonding strength
Still have much room for improvement.Moreover, the document does not refer to the oxygen permeability of its sealant, thus it can not learn that can the sealant be prevented
The only solar cell failure problem caused by oxygen permeates.
In view of above technical problem present in prior art, is badly in need of a kind of sealant used for solar batteries at present, it is solid
It is relatively low to change layer color inhibition, vapor permeability and oxygen permeability, and can be right in hot and humid and UV environment
The cohesive that solar cell module maintains a long-term stability.
