• FROM SAND TO THE SILICON WAFER — Steemit

    Crystallization of silicon. The wafer The high purity solar-grade silicon produced in the refining process described above, is polycrystalline and is not useful for photovoltaic applications. This is because solar cells need silicon wafers of good crystallographic quality, in order to achieve the higher efficiency.

  • What is a Silicon Wafer? Silicon Valley
    Ingot GrowthSlicingCleaningPolishingPackagingTo grow a ingot, the first step is to heat the silicon to 1420°C, above the melting point of silicon. Once the polycrystalline and dopant combination has been liquified, a single silicon crystal, the seed, is positioned on top of the melt, barely touching the surface. The seed has the same crystal orientation required in the finished ingot. To achieve doping uniformity, the seed crystal and the crucible of molten silicon rotate in opposite directionMeer bekijken op svmi
