What are the classifications of solar photovoltaic glass

Sep 30,2022

Author:

Classification of photovoltaic glass. Photovoltaic glass substrates for solar cells generally include ultra-thin glass, surface coated glass, low iron content (ultrawhite) glass and other types. According to the nature of use and manufacturing method, photovoltaic glass can be divided into three products, namely, the cover plate of flat panel solar cells, which is generally calendered glass; A thin film battery conductive substrate made of semiconductor materials with a thickness of only a few microns is plated on the surface of the flat glass; Glass of lens or reflector type used in the collector photovoltaic system. The characteristics and functions of these three products are completely different, and their added values are also very different.

What process is used to make solar photovoltaic 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.

How thick is photovoltaic glass used for solar energy?

Sep 30,2022

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 qualified
