The hottest photovoltaic antireflection glass will

Photovoltaic antireflection glass will replace traditional photovoltaic module glass into the mainstream

what is photovoltaic antireflection film, TCO glass

the core of photovoltaic power generation is to effectively absorb sunlight to improve photovoltaic power generation. Only the transmitted light will produce photoelectric effect on crystalline silicon cells, and finally convert solar energy into electric energy. For the low iron ultra white calendered glass used for photovoltaic modules, due to the half wave loss of the upper and lower surfaces, the reflectivity is about 4%, the absorption is less than 1%, and the visible light transmittance is generally not more than 92%. Because the light absorption rate of glass is small, the best way to improve the light transmittance is to reduce the reflectivity. The purpose of reducing reflection can be achieved by plating a layer of antireflection film with a thickness of one quarter of the length of the light wave

photovoltaic antireflection glass is a kind of glass deep-processing product obtained by using the principle of optical antireflection, coating antireflection film on the ultra white calendered glass substrate and then curing it, or forming antireflection layer on the surface of ultra white tempered glass through chemical methods, so as to make photovoltaic glass have higher light transmittance and improve the output power of photovoltaic modules. Generally, a single-layer photovoltaic antireflection film can increase the visible light transmittance by about 2%, preferably by 2.5% or even 3.5% on one side, which has a direct contribution to improving the efficiency of the photovoltaic industry and reducing the sharply rising costs in the solvent market

tco glass refers to transparent conductive oxide coated glass, which is a layer of transparent conductive oxide film uniformly plated on the surface of flat glass by physical or chemical coating methods, mainly including in (indium), Sn (TIN), Zn (zinc) and CD (cadmium) oxides and their composite multi oxide film materials, which are used as the conductive electrode of thin-film batteries. TCO glass mainly includes ITO glass, FTO glass and Azo Glass according to different coating materials

photovoltaic antireflection glass will become the mainstream module glass

because the transmittance of traditional photovoltaic module glass is only about 92%, about 8% of visible light is lost due to glass reflection and absorption. Photovoltaic antireflection glass by preparing a layer of antireflection film with the same life on the ultra white photovoltaic glass, the light transmittance of the glass can be increased by 2%, Assuming that the lighting conditions are proportional to the power generation, the power of every 1000W component using coated glass can be increased by W compared with ordinary components. With the increasingly fierce competition among photovoltaic module enterprises, photovoltaic antireflection glass will replace the continuous decline of traditional photovoltaic glass due to its high cost performance

although the new installed capacity of PV in 2012 may decline year-on-year, the oversupply of PV cells and modules is still expected, which is also the main reason why the market does not recognize the PV sector. However, the business of photovoltaic antireflection film is different from that of the main industrial chain products. It is still in the introduction period. On the premise that crystalline silicon cells account for 75%, the annual demand for photovoltaic glass is 130million square meters and 150million square meters respectively based on the use of 7.1 million square meters of photovoltaic glass per 1GW of battery modules. According to the production planning of existing enterprises, the global supply of coated glass in is about 54 million square meters, 72.5 million square meters and 78.5 million square meters. Therefore, the PV antireflection membrane will maintain the situation that the supply exceeds the demand and is penetrating the industry in recent years
