6 FAQs about [Polycrystalline silicon cells belong to information materials]
How are polycrystalline silicon cells produced?
Polycrystalline sillicon (also called: polysilicon, poly crystal, poly-Si or also: multi-Si, mc-Si) are manufactured from cast square ingots, produced by cooling and solidifying molten silicon. The liquid silicon is poured into blocks which are cut into thin plates.
What is polycrystalline silicon made of?
Polycrystalline silicon is a material made of misaligned (polycrystalline) silicon crystal. It occupies an intermediate position between amorphous silicon, in which there is no long-range order, and monocrystalline silicon. Polycrystalline silicon has an impurity level of 1 part per billion or less. For what is polycrystalline silicon?
How are polycrystalline solar cells made?
Polycrystalline silicon can also be obtained during silicon manufacturing processes. Polycrystalline cells have an efficiency that varies from 12 to 21%. These solar cells are manufactured by recycling discarded electronic components: the so-called "silicon scraps,” which are remelted to obtain a compact crystalline composition.
What are the advantages of polycrystalline silicon compared to wafer-based solar cells?
Fabricated as thin layers, polycrystalline silicon also features all advantages of thin-film technologies, namely low costs due to low material wastage with up to factor 100 less material compared to wafer-based solar cells, and the technically feasible monolithic fabrication of large area devices.
Are polycrystalline silicon based solar cells resonable?
Basic polycrystalline silicon based solar cells with a total area efficiency of app. 5% has been fabricated without the involvement of anti-reflecting coating. This is a resonable result considering that comercial high efficiency solar cells have a con-version efficiency of about 22%, as outlined in chapter 1.
