The partially-crystallized form is often called polycrystalline silicon, or polysilicon for short. The optical constants (n and k) of amorphous and polysilicon are unique to the deposition conditions and must be measured for an accurate thickness measurement. Roughness and possible grading of the silicon film crystallinity must also be taken ...

Polycrystalline silicon is a high purity, poly-si form (Fig. 2.5) used by the PV industry as a raw material. A chemical purification process known as the Siemens process produces poly-Si from metallurgical-grade silicon. This process involves distilling volatile silicon compounds at high temperatures and decomposing them into silicon [10]. In ...
