Description

A kind of ultraviolet light solidification packaging adhesive film and solar cell module
Technical field
The invention belongs to photovoltaic encapsulation glue film field, it is related to a kind of ultraviolet light solidification packaging adhesive film and solar battery group Part.
Background technique
The energy is valuable source for the survival of mankind, and the environmental problem increasingly shown then discloses conventional energy resource can not be again Raw drawback and its subsidiary using environment as the sky high cost of cost.In order to realize the sustainable development of the energy and environment, various countries It all promotes the use of clean energy in Devoting Major Efforts To Developing, photovoltaic power generation is also one of prior development direction.However, although photovoltaic power generation is in the energy Middle accounting is significantly increased, but relies primarily on support on policy and subsidy of the government to new energy, and market development is still limited by solar energy Battery component is at high cost.One of an important factor for influencing component cost is exactly production efficiency, this mainly depends on packaging adhesive film again Curing time.General components curing time is up to 15-25 minutes at present, has seriously affected component package efficiency, in automation journey It spends under environment higher and higher, packaging efficiency is particularly important.Packaging adhesive film curing time is shorter, and efficiency is higher, energy consumption is smaller, band The benefit come is self-evident.
Current most widely used glue film curing method is that heat causes chemical method, this is a kind of traditional cross-linking method, main Peroxide decomposition is set to generate free radicals and cause a series of free radical at high temperature by adding peroxide initiator Reaction, makes polymeric matrix crosslink to form reticular structure.This method development is very mature, but time consumption and energy consumption, and not easily-controllable Crosslinking degree processed.In order to improve curing efficiency, also usually uses raising laminating temperature and increases the means of peroxide additive amount, But the problems such as both methods generates bubble when being easy to cause lamination, remains excessive peroxide damage component ageing-resistant performance.
In recent years solar double-glass assemblies with photovoltaic glass replace backboard, because its without frame, stronger anti-PID ability, reliability, The advantages that weatherability, becomes photovoltaic industry development trend.But it is limited by process conditions, bubble, broken is easy to produce in production process The bad phenomenons such as piece, displacement cause yield rate lower, and production cost increases.Solidify packaging adhesive film according to ultraviolet light, introduces purple External irradiation technique can greatly shorten lamination times, component lamination temperature be reduced, to avoid bubble, excessive glue, displacement etc. bad Phenomenon.
There are also patents to propose the preparation method of UV crosslinking glue film at present, and patent CN 102689386A is by adding Enter photoinitiator and photosensitizer preparation UV crosslinking type EVA adhesive film, but it only passes through addition free radical photo-initiation and reaches purple The effect of external crosslinking, cross-linking efficiency may be lower, and not can avoid the oxygen inhibition in ultraviolet irradiation.The ground state of general substance It is singlet, O2Stable state be triplet state, there are two the identical unpaired electron of spin direction.Therefore, it can be with freedom The polymerization reaction of base competes and consumes free radical.Oxygen inhibition can frequently result in that glue film surface layer is uncured and stickness or solidification path The problems such as low is spent, to influence the long-term reliability of glue film.
Summary of the invention
