Photovoltaic glass is a special type of glass that converts natural light into electricity by encapsulating solar cell components in a glass layer. Low-iron tempered glass or double-layer glass is usually used, and the surface is coated with an anti-reflective coating and a transparent conductive layer.
Float glass is a common glass manufacturing process, the production process of glass raw materials (such as silica sand, sodium carbonate, limestone, etc.) after melting, from the glass bath above the uniform flow, the cooling solidified into flaky glass. This technology can produce high-quality, uniform thickness glass, and has a wide range of uses.
The difference between photovoltaic glass and float glass is mainly reflected in the following aspects:
Different uses: photovoltaic glass is mainly used in the manufacture of solar panels, while float glass is widely used in construction, automobiles and other fields;
Different materials: photovoltaic glass usually uses special materials such as low-iron tempered glass or double-layer glass, while float glass is produced using ordinary glass raw materials through a special process;
The manufacturing method is different: photovoltaic glass needs to be coated with an anti-reflective coating and a transparent conductive layer on the surface, and the solar cell module is encapsulated in it. Float glass, on the other hand, is made from glass flakes by melting raw materials.
Different performance requirements: photovoltaic glass needs to have a certain transmittance, reflectivity and wind pressure resistance and other special properties, and float glass mainly requires uniform thickness, high strength and light transmission performance.
