Abstract
The present invention discloses a kind of surface encapsulation film of solar panel, and for surface encapsulation film using polyester film as substrate, the polyester film surface is equipped with multiple protrusions, which is that UV light-cured resin is formed in such a way that UV is transferred in polyester film surface.The present invention also provides a kind of production methods of the surface encapsulation film of solar panel.Protrusion in surface encapsulation film of the invention is can not only to improve the performance of polyester film surface using UV light-cured resin as material, moreover it is possible to improve the weather resistance of polyester film, extend the service life of polyester film.
Description
Technical field
The present invention relates to the surface encapsulation film of a kind of solar battery hyaline membrane more particularly to a kind of solar panel and
Its production method.
Background technique
With the development of society, photovoltaic industry has become a big important development direction of new energy industry, especially too
The development of positive energy battery technology is more rapid, and technology is more and more mature, and the installation of global photovoltaic power generation unit in 2017 is
94.6GW is installed as 415GW by what photovoltaic power generation unit global by 2017 added up.In many regional solar battery in China
It promotes the use of a large area already, China photovoltaic power generation unit generation amount in 2017 is 68GWp, Zhan Quanqiu photovoltaic generator in 2017
72% or so of group generated energy.By by 2017, the accumulative photovoltaic power generation quantity of China is 133GWp, accounts for the accumulative photovoltaic power generation in the whole world
The 32% of amount, China are to become qualified photovoltaic power generation big country.Other than large-scale photo-voltaic power generation station, small-sized in recent years,
