Abstract
The invention discloses a kind of solar cell backboard film and preparation method thereof, the solar cell backboard film is made of the raw material of following parts by weight：12 20 parts of butyl rubber, 20 32 parts of Kynoar PVDF, 4 10 parts of dipropylene glycol, 12 24 parts of polyester powder, 28 parts of Sodium Polyacrylate, 4 10 parts of benzalkonium chloride, 20 30 parts of polystyrolsulfon acid, 8 14 parts of silica, 6 10 parts of polyetherimide, 28 parts of 2,6 di-t-butyl, 4 methylphenol, 6 12 parts of sodium carboxymethylcellulose, 17 parts of poly- trimethyldihydroquinoline, 0.2 0.8 parts of dilauryl thiodipropionate, 15 parts of hindered amine light stabilizer, 0.6 1.8 parts of dioctyl phthalate；The solar cell backboard film of gained of the invention can effectively extend solar energy backboard service life, enhance that solar energy backboard is heat-resisting, ageing-resistant, vapour resistant through performance, it with higher breakdown voltage property, and can completely be bonded together, be not easily stripped with base material；It has a extensive future.
Description
Technical field
The present invention relates to solar cell material preparing technical field, specifically a kind of solar cell backboard film and its system
Preparation Method.
Background technology
Earth environment pollutes and energy shortage problem is on the rise, and solar cell power generation is to solve both of these problems most
One of effective way；Solar power generation is that directly the visible light of the sun is changed into using the quantum effect principle of the semiconductors such as silicon
Electric energy, but since it faces atrocious weather, it would be desirable to which a kind of material protects silicon chip of solar cell, straight in face of the sun
We generally protect silicon chip to the one side penetrated using glass, and reverse side then needs to protect using solar battery back film；The sun
The notacoria of energy battery component is located at the back side of solar panel, and protection and supporting role, solar cell are played to cell piece
The notacoria of component plays a key effect to battery, output power, security reliability；And the notacoria of the prior art is weather-proof
Property, water preventing ability, insulating properties and resistance to ag(e)ing it is poor, can not ensure that battery is reliable, stablize, use safely for a long time, influence property
Energy and service life increase maintenance cost, therefore, there is an urgent need to propose new solar cell backboard membrane technology, in solution
State problem.
Invention content
The purpose of the present invention is to provide a kind of of low cost, simple for process, weatherability, water preventing ability, ageing-resistant performance are good
Solar cell backboard film and preparation method thereof, to solve the problems mentioned in the above background technology.
