Thin-film solar cells are gradually popularizing in the photovoltaic industry

At present, most of the main materials used in the global photovoltaic industry are crystalline silicon cells, and monocrystalline silicon cells and polycrystalline silicon cells dominate the field of photovoltaic panels
.
The second-generation solar cell, thin-film solar cell market, is now quietly rising, with its unique light weight, good light transmission and other advantages to open up a new field
.

Thin-film solar cells are a layer of thin film prepared into solar cells, which use very little silicon, which is easier to reduce costs and is a new building material
.
Compared with crystalline silicon solar cells, although its area output power is slightly lower and the cost of supporting products is high, it can be applied to residential roofs, thin-film solar building integration, agricultural greenhouses, vehicle and ship zenith and other fields with its advantages of light weight, good light transmittance, flexibility and bendability, and can also build large-scale ground power stations to create mobile charging products
.

Thin-film solar cells can be manufactured using inexpensive glass, plastic, ceramics, graphite, metal sheets and other different materials as substrates, and the laboratory conversion efficiency has reached more than 20%, and the stable efficiency of large-scale mass production is about 13%.

In addition to the plane, thin-film solar cells can also be made into non-planar structures because of their flexibility, and their application range is large, and they can be combined with buildings or become part of
the building body.
