a-Si Thin Film Solar Energy Power-Bapv Solar Roofs

In contrast to traditional crystalline silicon PV that is cut from solid crystalline material, thin film PV is composed of thin layers of semiconductor materials grown on a glass or flexible substrate and sandwiched between front and back contacts. Our thin film PV is composed of an amorphous silicon (a-Si) layer, PVB (Polyvinyl Butyral), TCO (Transparent Conducting Oxide) Glass and Tempered Glass.

XUSHUANGS Solar's a-Si technology has the dual advantage of using environmentally safe and abundant silicon, and utilizing the tremendous silicon-based manufacturing infrastructure in the semiconductor industry. The end result is that the customer receives a high quality product, manufactured through time-tested methods, for the lowest price.

Advantages of XUSHUANG a-Si thin film solar technology:
1. Larger generating capacity: According to the test, in the same condition, a-Si thin film cell could generate 10%-20 more power than Mono crystalline silicon and Poly crystalline silicon.
2. Good performance in weak light situation, high charging efficiency: The material of a-Si thin film absorption coefficient is in range of whole visible light, it's more suitable for weak and hard light in actual use.
3. Mass production possible because of existing infrastructure, has the most mature mass production equipment base
4. Does not require use of scarce raw materials
5. Without Toxic elements Cadmium (CD) or Selenium (Se), it's totally clean energy, harmless for the environment.
6. Can be used for a wide array of applications
7. Effective integration into building interfaces
8. Long term reliability and performance proven
9. Increasing conversion efficiency and stability
