The manufacture of solar energy module is comprised of the coating of at least two material members.Material members can be rigid member, sealant, active member or back side member.Rigid member can comprise glass, reinforced plastics or pottery.Sealant can comprise EVA, PVB and silicon.Active member can comprise solar cell, crystal or the film of any type.Back side member can comprise polyvinyl fluoride.These materials are generally known in the production of solar energy module, especially in the lamination solar energy module.Yet they can also use in other processing methods, such as curtain coating (curtain coating) or injection mo(u)lding.
When a plurality of layer (being called coating) of mobile a pile, the air-flow on (or a plurality of) member can make member from its/displacement of their desired locations.Correspondingly, can not be as the mobile so fast coating of expectation.
And, during lamination, in some process, the material of the member of coating before producing vacuum with together with coating is pressed in before heat up.If the top member of coating is EVA, EVA may melt.Now, along with producing vacuum, be captured on the bubble blast that the air below EVA can make EVA form.In addition, be captured on air below partial melting EVA and may no longer feel and upwards promote from top any pressure and by EVA, EVA is expanded.
In addition, excessive if the bubble formed in EVA like this becomes, it may pop, and stays the zone that there is no EVA.If bubble popped in its hour, EVA may be pulled to side a bit, but all the other spaces in EVA may be small enough to during lamination, be closed after a while when EVA is melted and because applied pressure starts to flow.If bubble is larger, EVA may be pulled to side too much and filled gap in processing after a while, stay and have less or there is no the scope of EVA, the adhesive function that may collect gas and moisture during lamination and make EVA is not so effectively and damage battery along with passage of time.In addition, space can in module, be formed on aesthetic on not pleasant bubble.
