What's the difference between photothermal glass and photovoltaic glass?

In recent years, photovoltaic technology is more popular, such as installing photovoltaic power generation and photovoltaic glass in self-built houses. What is the difference between photovoltaic glass and photothermal glass?

What's the difference between photothermal glass and photovoltaic glass?

1, photothermal and photovoltaic are different types. Photothermal absorption of solar radiation by materials can produce different wavelengths, and then this light energy can be converted into heat energy, which has the function of heating, so the produced photothermal glass has the function of concentrating light energy and is widely used in industrial production and life.

2. Photovoltaic glass is another kind, which can also be called photoelectric glass. Using solar energy and installing photovoltaic modules can generate electricity through radiation. The main components are glass and batteries, including a special metal wire, thus forming a high-tech glass product. It can adapt to the temperature difference between day and night and has a beautiful appearance. Therefore, the principles between them, including the scope of use, are also very different. For example, photovoltaic can also be used as the material of curtain wall.

Second, what is the difference between photovoltaic glass and ordinary glass?

1. From their elemental composition, the iron content of these two glasses is basically above 0.2% if they are common, but the iron content of photovoltaic type is relatively low, which is controlled between 0.0 15%-0.02%.

2. If we compare the visible light transmittance of the two, the ordinary type is basically around 88%, and the latter reaches more than 9 1%. If we compare the high temperature resistance of the two, the high temperature resistance of ordinary glass is not particularly good, basically reaching 80-90 degrees is the limit, but the high temperature resistance of photovoltaic type is very outstanding, and it can withstand high temperatures above 500 degrees.

3. On the other hand, photovoltaic is better than ordinary type in both corrosion resistance and impact resistance.

My conclusion: The above is the difference between photovoltaic glass, photothermal glass and ordinary glass. There are many kinds of glass, and their properties are quite different because of their different compositions and principles.
