Abstract
The invention relates to an anti-PID coating and a method for preparing and using the same, in particular to an anti-PID coating for photovoltaic module glass and a method for preparing and using the same. The coating is a UV curing anti-PID coating, and its raw materials include: 20-50 parts of monomer, 5-30 parts of UV curing agent, 10-40 parts of oligomeric resin, and 0.5-5 parts of auxiliary agent. When preparing, all raw materials are mixed and stirred evenly to form a solution; when used, it is firstly coated on glass, and then the inner side of the glass is irradiated evenly with ultraviolet rays. The raw materials of the invention are easy to obtain, the preparation and use methods 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...
