For a long time, people have been working hard to study the use of solar energy. Solar photovoltaic glass is a type of special glass that is laminated into a solar cell, is capable of generating electricity from solar radiation, and has associated current extraction devices and cables. People should not be unfamiliar with it, but not particularly aware of it! Today, Xiao Bian gave you an introduction to the related contents of solar photovoltaic glass . I hope to help you. For more information on glass, please continue to pay attention to information on this site.
Solar photovoltaic glass
Solar photovoltaic glass consists of low-iron glass, solar cells, film, back glass, special metal wires, etc. It is a kind of solar cell film sealed in the middle of a low-iron glass and a back glass. It is the most novel. High-tech glass products for construction. Low-iron glass is used to cover solar cells to ensure more light transmission and generate more power. The tempered low-iron glass has a higher strength, can withstand greater wind pressure and a large temperature difference between day and night.
Classification of solar photovoltaic glass
Solar photovoltaic glass is a type of special glass that is laminated into a solar cell, is capable of generating electricity from solar radiation, and has associated current extraction devices and cables. It has beautiful, light-controllable, energy-saving power generation and it does not require fuel, no waste gas, no waste heat, no waste residue, no noise pollution advantages, a wide range of applications, such as: solar smart windows, solar pavilions and photovoltaic glass building roof , And photovoltaic glass curtain wall and so on.
Solar photovoltaic glass can be divided into crystalline silicon photovoltaic glass and thin film photovoltaic glass two categories, including the most common use of crystalline silicon curtain wall, he is divided into two types of monocrystalline silicon and polysilicon. The following describes a photovoltaic glass is composed of glass-PVB (EVA) film - solar cell - PVB (EVA) film - glass a total of 5 layers (see below), similar to the commonly used laminated glass in construction, with Very good security. A 5% to 80% light transmittance photovoltaic glass can be made by controlling the cell gap and the edge void between double-sided glass.
The hollow photovoltaic glass replaces the outer glass of the insulating glass with a double glass-bonded photovoltaic module, and has more synthetic hollow steps than the double glass-bonded photovoltaic module in the production process. There is no essential difference. Due to the fact that the efficiency of power generation of crystalline silicon photovoltaic modules decreases at high temperatures, hollow photovoltaic glass is generally used in non-high temperature areas. Thin film photovoltaic glass is characterized by light weight, thin thickness, bendable, easy to carry, and good low-light-lightness. In the case of weak light in the morning and in the evening, the power generation effect is better than that of single-crystal silicon battery, but there is no conversion efficiency of traditional silicon crystal battery. .
The above is the introduction of related contents of solar photovoltaic glass. I hope to help you. For more information on glass, please continue to pay attention to information on this site.
