With the development of industry, there are various types of glass. The glass has excellent performance and can be used in many occasions. There are painted glass and hot melt glass suitable for indoor use, tempered glass and laminated glass suitable for special occasions, as well as convenient and durable frosted glass and dimming glass, etc. Here is an introduction to photovoltaic glass.

photovoltaic glass introduction:

Photovoltaic glass is a special glass that can generate electricity from solar radiation by laminating solar cells, and has related current extraction devices and cables. It has the advantages of beautiful appearance, controllable light transmission, energy-saving power generation, no fuel, no waste gas, no waste heat, no noise pollution, and is widely used, such as solar smart windows, solar pavilions and photovoltaic glass building ceilings, and photovoltaic glass curtain walls, etc. Photovoltaic glass can be divided into crystalline silicon photovoltaic glass and thin film photovoltaic glass two categories, of which the curtain wall is commonly used in crystalline silicon, and divided into monocrystalline silicon and polycrystalline silicon two categories.

photovoltaic glass uses:

Solar photovoltaic glass is a kind of special glass that can generate electricity from solar radiation by laminating solar cells, and has related current extraction devices and cables. It is composed of low-iron glass, solar cells, film, back glass, special metal wire, the solar cell through the film sealed in a piece of low-iron glass and a piece of back glass in the middle, is a novel building with high-tech glass products. The low-iron glass is used to cover the solar cell, which can ensure high sunlight transmittance. The tempered low-iron glass also has stronger wind pressure resistance and the ability to withstand large changes in temperature difference between day and night. Widely used in building curtain wall, photovoltaic roof, shading, solar power generation system and many other fields.

photovoltaic glass industry status and prospects:

In recent years, the photovoltaic glass industry has developed rapidly. With the lightweight of components and the continuous production of new technologies, the thickness of cover glass will develop to thin-sheet, and the market share of 3.2mm thick front cover glass will continue to be compressed. It is expected that by 2025, 2.5mm front cover glass will become the first market share. Other (front cover glass below 2.0mm) thickness of the front cover glass market share will also increase rapidly. At the same time, the cost of power generation will be reduced by 7% for every 1% increase in the photoelectric conversion efficiency of solar cells. In order to improve the photoelectric conversion efficiency, in terms of photovoltaic glass, the focus is to improve the light transmittance, the average light transmittance of the original photovoltaic glass in the industry is about 91.6 percent, and there will be a big improvement in the future. At present, the domestic epidemic is under control as a whole, and the peak of the epidemic in some mainstream photovoltaic installed markets overseas has passed. Considering the construction progress of domestic bidding projects and parity projects in 2019-2020, as well as the release rhythm of PV demand such as household PV and UHV bases, we expect domestic demand to recover strongly in the second half of the year, with domestic PV installed capacity expected to reach 45GW for the whole year, and the boom is expected to continue until 2021. Among them, 2020Q4 is expected to achieve more than 20GW installed, forming a phased installation peak.

In short, with the development of industrial economy, the city's architecture and decoration have also developed. The characteristics of glass such as light transmittance and durability, coupled with its beauty, make people more willing to choose glass to make the building look beautiful and fashionable outside, and do not affect the internal light transmittance. It can also combine some special materials to add some additional functions to the glass, such as heat preservation, sound insulation, etc, the photovoltaic glass introduced today is a major development witness of industrial science and technology, and there will be better in the future, with more functions, regions, and uses, and more safety.
