Photovoltaic (pv) power plant manufacturers to introduce you to a photovoltaic cell module glass surface

Photovoltaic hair cells usually adopts the panel glass is toughened glass, its low content of iron, glossy or matte white. We also often called smooth glass float glass, suede or rolling glass. We use most of the thickness of the glass panel is commonly

for photovoltaic cell components of flat glass is usually low iron tempered glass, ultra white smooth surface or suede. We also often called smooth glass float glass, suede or rolling glass. We use most of the thickness of the plate glass is commonly 3. 2 mm and 4 mm, building material thickness for 5 - type solar photovoltaic modules 10 mm, but no matter how is the thickness of the plate glass, the light transmittance were required to be over 90%, the spectral response of the wavelength range of 320 ~ 1100 nm, for greater than 1200 nm infrared light with high reflectivity. Because of its iron content is lower than common glass, so the glass transmittance increased. In general, common glass from the edge is green. Because of this glass less than common glass iron, look from the edge than common glass is white, so this is super white glass. Suede refers to in order to reduce the reflection of sunshine and increase the amount of incident light, glass surface by physical and chemical methods made fluffy. Of course, through the use of sol-gel Gel nanomaterials and precision coating technology ( Such as magnetron sputtering, double-sided soaking technology) In the glass surface coated with a layer of thin film containing nanomaterials. Coated glass can not only significantly increase the transmittance of plate glass is more than 2%, also can significantly reduce the light reflection, and self-cleaning function, reduces the panels on the surface of the rain, dust and other pollution, keep clean and reduce light attenuation, improve the efficiency of power generation 1. 5% ~ 3%. In order to increase the strength of the glass against the impact of dust storm and hail, long-term protection of solar cells, we on the flat glass steel processing. First of all, the level of toughened glass furnace heated to a temperature of about 700 ℃, and then use cold air rapid cooling uniformity, glass surface compressive stress evenly, internal tensile stress in the formation, thus improve the glass bending and impact resistant performance. Toughened flat glass strength after 4 - greater than that of the common glass 5 times.
