Abstract: 

Nowadays, electrical power generation by photovoltaic conversion of solar light continuously

increases. This can be attributed to the development of new photovoltaic materials, which have led

to the price reduction of the watt-hour generated by photovoltaic means. An interesting approach

to the solar cells cost reduction consists of using polycrystalline semiconductor thin films. The IIIV

semiconductor compound, CdTe, has suitable electrical and optical properties as photovoltaic

and high-energy radiation sensor material. As an absorber material for thin-film-based solar cells,

CdTe holds the potential to fabricate high-efficiency solar cells by means of low-cost technologies.
