What are the raw materials for solar panels?

Do you know what the raw materials of solar panels are? Let you briefly understand the following text:

<br> 1. High efficiency solar cells (16.5% or more) of a single crystal silicon solar chip package, to ensure adequate power generation of the solar cell panel.

2. Glass <br> low Steel of suede glass (also called white glass), a thickness of 3.2mm, in the wavelength range of the spectral response of the solar cell (320-1100nm) light transmission rate of 91% for greater than 1200 The infrared light of nm has a higher reflectivity. The glass is also resistant to radiation from the sun's ultraviolet light, and the light transmittance does not decrease.

3.EVA
A high-quality EVA film layer with a thickness of 0.78 mm added with an anti-UV agent, an antioxidant and a curing agent is used as a sealing agent for the solar cell and a connecting agent with the glass and the TPT. It has high light transmittance and anti-aging ability.

4.TPT
The back cover of the solar cell - the fluoroplastic film is white, reflecting the sunlight, so the efficiency of the component is slightly improved, and because of its high infrared emissivity, it can also reduce the operating temperature of the component, and is also beneficial to Improve the efficiency of components. Of course, the fluoroplastic film firstly has the basic requirements of aging resistance, corrosion resistance, and air resistance required by the solar cell packaging material.

5. Border <br> The aluminum alloy frame used has high strength and strong mechanical impact resistance. It is also part of the value of home solar power. Its role is to convert the solar radiation capacity into electrical energy, or send it to the battery for storage, or to drive the load.
