* The cell is produced from polycrystalline materials and glass, which is a potentially much cheaper construction than bulk silicon.  *The chemical and physical properties of the semiconductors are such that the polysilicon thin-films can be deposited using a variety of different techniques (see below).  * CdTe has a bandgap which is very close to the theoretically-calculated optimum value for solar cells under unconcentrated AM1.5 sunlight.  * CdTe has a high absorption coefficient ( \( \alpha > 5\times 10^{5} \) ) , ),  approximately 99% of the incident light is absorbed by a layer thickness of only 2µm, cutting down on materials cost.
