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 …
The films of pc-silicon cells are exploited to get some advantages over the bulk silicon (Si) solar cells. This is a most abundant material, which is why it is widely used for film technologies such as cells. Toxicity is a major problem for some of the technologies such as cadmium telluride (CdTe) base cells but not for silicon cells.
