Description

General description

CdTe is a photonic material. Crystal structure of CdTe is zinc blende structure. 3CdTe is usually an obvious choice for photovoltaic applications because of its; low cost, direct band gap (1.44eV),3 high absorption coefficient, easily doped with p and n type dopants by several preparation techniques. 2

Application

Cadmium telluride may be used in photovoltaic solar cells as the window layer. CdTe was used in the preparation of an Au/Cu2Te/CdTe/CdS/TCO/glass heterostructure for solar cell.
