Photovoltaic glass is a special glass used in photovoltaic modules, which has the characteristics of high light transmittance, high strength and strong weather resistance. It is one of the key components to ensure the efficient operation of photovoltaic modules.
Type:
Ultra-white calendered glass: This is currently the most commonly used type of photovoltaic glass. Its iron content is very low, which can reduce the absorption and reflection of sunlight and improve the photoelectric conversion efficiency of photovoltaic modules. The embossed structure of the glass surface can increase the incident angle and scattering effect of light, so that the light is more evenly distributed in the component.
Surface coated glass: By plating a special film on the glass surface, such as anti-reflection film, the light transmittance of the glass is further improved, the light reflection loss is reduced, and the power generation efficiency of the photovoltaic module is improved.
TCO coated glass: transparent conductive oxide coated glass, mainly including indium (In), tin (Sn), zinc (Zn) and cadmium (Cd) oxide and its composite multi-component oxide film. The intermediate semiconductor layer of thin-film solar cells has almost no lateral conductivity and requires the use of TCO glass to collect the current of the cell. Its high light transmittance and transparency properties allow most of the sunlight to enter the absorption layer.
Production process:
Raw film production: quartz sand, soda ash, feldspar, dolomite, limestone, mirabilite and other raw materials through mixing, melting, rolling, annealing and cutting five steps, to obtain untreated photovoltaic raw film semi-finished products. Melting, forming and annealing are the core links of the original production line, and problems in any one link will affect product quality and production rate.
Deep processing: the original sheet is tempered after edging to obtain a tempered sheet; or tempered coating to obtain a coated sheet for component packaging. Tempering can enhance the strength of the glass, and the coating is to coat a layer of anti-reflection film on the tempered glass to enhance the light transmittance.

"I heard that the subsidy for new energy vehicles will be canceled, do I still need to buy it? Is it necessary to hurry up before the official cancellation?" recently, another "disturbing" statement in China's new energy industry related to this is that subsidies for photovoltaic power generation should be abolished, which is commonly referred to as the "531 New deal". In the future, the installation cost of household distribution power stations will increase greatly, and there will not be so much profit, and the industry will have to be reshuffled. What exactly is the truth?
