Anti-reflective coating low iron solar glass Low-iron patterned solar glass, combined with nanometer anti-reflective coating technology, is applied for solar modules. It increases solar transmittance by way of decreasing light reflectance, thus increasing the solar cell efficiency. Besides, it reduces the reflected glare of the glass and the pollution caused by the reflectance to the environment. The super water-wet behavior of the coating could in some degree protect the dust and dirt from shading the light and improve the self-cleaning of the glass so that the solar cell could maintain high efficiency.
