What are the differences between solar coated glass and photovoltaic glass
Solar coated glass is divided into low radiation glass or LOW-e glass for building curtain wall, or glass with sound insulation and heat insulation functions of some coating layers. It is uncertain whether it refers to this part.
In addition, there is a TCO transparent conductive film coated glass for the amorphous silicon glass of solar energy. It is an amorphous silicon film module made by etching, welding wires and other processes. It also belongs to the field of solar energy coating, or can be said to be a photovoltaic glass.
In addition, some commonly known double glass modules in recent years are frost wave photovoltaic modules, which are composed of two pieces of glass and a thin layer of super white subway tempered glass+film+silicon cell sheet+film+tempered glass base plate on the upper surface. They belong to photovoltaic glass.
There is also a common one, called ultra white low iron textured (embossed) glass cover, which is usually a 3.2mm tempered ultra white embossed glass+film+silicon cell sheet+film+backplane battery module. It can be divided into monocrystalline silicon and polycrystalline silicon cell modules according to different silicon chips. However, this glass can also be coated with AR antireflection and antireflection coatings, which is also a kind of photovoltaic glass, also called solar AR coated glass.
First, weigh the glass raw materials according to the formula requirements, and then mix them evenly. Then, use the feeder to put the batch into the glass furnace. By controlling the temperature in the glass furnace, the batch can be melted at a high temperature of about 1600 ℃. Control certain temperature requirements to make the glass complete the process of clarification, homogenization, cooling, etc., and then make the glass by calendering or float molding. It is mainly to control the iron content in the process of batching, melting and molding, so that the transmissivity of the glass can reach 91.6%, and the defects should be lower than a certain requirement.View More
Generally, glass with a thickness of 3.2cm is used. (3.2cm/4cm/) The strength is tested under certain conditions: 227 grams of steel balls fall freely at a height of 1 meter, and the glass does not break Generally speaking, the light transmittance can reach 91% as long as the photovoltaic glass is professionally produced The steel degree you mentioned is also obtained under certain operation: more than 40 grains within the range of 50 * 50 are qualifiedView More
