Photovoltaic glass ultra-white thermal glass

The encapsulated glass used in solar photovoltaic modules (or custom solar panels), the current mainstream products are low-iron tempered embossed glass, the solar cell module has high requirements for the transmittance of tempered glass, which must be greater than 91.6%, and has a higher reflection for infrared light greater than 1200 nm. rate.

Ultra-clear glass is a type of solar glass, and basically ultra-white glass is embossed for use on solar energy. The purpose of embossing is to increase the light transmittance. The reason is very simple. The sun shines a lot of light on a plane, so there is less to the silicon.

One is to apply an anti-reflection coating on the surface of the photovoltaic glass to improve the light transmittance of the photovoltaic glass, and the second is to use a self-cleaning anti-reflection film. Photovoltaic glass achieves self-cleaning effect while increasing penetration.

Photovoltaic glass is one of the best materials to protect crystalline silicon and has high self-transmission rate for a long time. Therefore, the optical properties of photovoltaic glass are an important factor outside the crystalline silicon technology.

The principle of roll coating method for producing AR coated photovoltaic glass is to prepare nano silica sol and porous silica film by sol-gel method. First, a silica sol is prepared by using tetraethyl orthosilicate (TEOS) as a precursor and ammonia as a catalyst.

Physical tempered glass, also known as quenched tempered glass (heats the metal workpiece to a suitable temperature for a period of time, then immerses it into the quenching medium for rapid cooling). This kind of glass is under internal tension and externally stressed.
