Abstract

The invention relates to an anti-PID coating and a preparation method and a use method thereof, and in particular relates to an anti-PID coating for photovoltaic module glass and the preparation method and the use method thereof. The coating is a UV-cured PID-resistant coating and is prepared from the raw materials of, by weight, 20 to 50 parts of a monomer, 5 to 30 parts of a UV curing agent, 10to 40 parts of oligomeric resin and 0.5 to 5 parts of an auxiliary agent. During preparation, the raw materials are uniformly mixed and stirred to prepare a solution. When in use, the coating is firstly coated on glass, and then ultraviolet rays are used for uniformly irradiating the inner side of the glass. According to the invention, the raw materials are easy to obtain; the preparation and usemethods are simple and convenient; and the effect is obvious.

Description

technical field [0001] The invention relates to an anti-PID coating solution and a method for preparing and using the same, in particular to an anti-PID coating for solar photovoltaic module glass and a method for preparing and using the same. Background technique [0002] With the continuous development of solar photovoltaic technology, the industry has paid more and more attention to the potential induced degradation effect (hereinafter referred to as PID) of photovoltaic modules, which has become one of the important factors affecting the efficiency of photovoltaic modules. [0003] The structure of conventional photovoltaic modules is mainly: upper photovoltaic glass-upper packaging film-cell sheet-lower packaging film-lower backplane (or photovoltaic glass). However, the cause of PV module PID has not yet been fully studied, but according to the existing research data, the industry generally believes that the Na in the module + The movement is one of the important caus...
