AR Coated Anti-reflective Glass, AR Coating Equipment For Which Fields
AR coated anti-reflective glass has a lower reflection ratio than other ordinary glass, and is a glass with a special treatment on the surface of ordinary glass. By coating the surface of ordinary tempered glass, it improves the light transmittance of the tempered glass surface to achieve the purpose of easy cleaning, and AR coating equipment also extends the service life of the glass.
AR film, also known as transmission enhancement film, is a surface optical coating that increases light transmission by reducing the reflection of light, a feature important to astronomy, and increases contrast by reducing scattered light in the system. When light is reflected secondarily on a transparency-enhancing film, the original reflected light interferes with it, thereby attenuating the reflected light. The principle of transparency film: According to the conservation of energy, when the energy of light remains constant, the reflected light is reduced and the transmitted light is increased. Infrared, visible and ultraviolet light are selected by determining the wavelength of the film. The thickness of the film determines the wavelength of the reflected light it acts on, and a transparent film structure with different refractive indices is what many coatings have.
Solar cell modules, photothermal, architectural, automotive glass and other fields are mainly used in the application of AR coated glass. The general surface of LCD monitors and LCD TVs are easily damaged by scratches, without adding front glass in front, and with small viewing angle. But if installed with AR glass, these problems will be able to solve. AR glass is mainly used for display devices to protect the screen: such as LCD TV, PDP TV, laptop, desktop computer display, advanced instrument panel, touch screen, photo frame glass, etc. AR glass can be electronic products to improve the transmittance to reduce its reflectivity.
Super white embossed glass can improve the photoelectric conversion efficiency of silicon cells, mainly used for solar thermal, photoelectric conversion system of monocrystalline silicon and polycrystalline silicon solar photovoltaic cell light harvesting panel, must have the lowest possible reflectivity, as high as possible sunlight transmission rate, in order to make the electrode plate fully absorb the sun's energy. Its own low iron content formula also significantly reduces the solar energy absorption rate, and its surface linting treatment can also reduce the light reflection rate. If on top of this, a layer of reflective enhancement film is plated, it can - achieve a relatively high solar energy conversion efficiency.
After the surface of ordinary ultra-white glass is coated with transmissive film, it can effectively reduce the solar reflection ratio on the surface of the glass, and then the anti-reflective coated glass obtained after tempering treatment can improve the energy transmission rate, and finally improve the power generation efficiency of solar cells. It is a new technology and product in the international arena. The photovoltaic reflective glass can increase the visible light transmission rate by 2.5%, which in turn can improve the conversion efficiency of crystalline silicon photovoltaic modules. 1% difference in conversion efficiency means about 6-7% difference in cost.
