On photovoltaic cover glass, single-layer anti-reflective (AR) coatings often present the problem of not being able to balance light transmittance, weather resistance, and stain resistance. Dual-layer AR coatings have been proven to be an effective form of coating that can significantly improve the light transmittance of glass, particularly in terms of actual power output of the modules. However, dual-layer coatings are not easy to control in actual production, with the thickness and uniformity of the film layers being difficult to ensure, leading to a low yield rate, making dual-layer coating a technology that many glass companies both love and fear for its innovation.

Chenguang Company, in collaboration with several domestic glass processing enterprises, has overcome various challenges such as single-layer film thickness control, uniformity adjustment, tempering warp suppression, and color appearance control, and has successfully launched the CG108 dual-layer AR coating solution. The dual-layer solution from Chenguang is highly adaptable, offers significant gains (0.2-0.3), has an attractive appearance, and is particularly stable in production, making it one of the best dual-layer solutions in the industry. Chenguang Company promises to provide a complete technical solution and initial production support to ensure that customers can quickly achieve mass production with dual-coating.
