Product Description




Introduction
The semiconductor compound cadmium sulfide(CdS) has a photovoltaic effect and can be used to make a solar cell. Due to its special electrical, optical, semiconductor and optoelectronic properties, the CdS substrate has received extensive attention. The II - VI crystals are likely to be used for highlight shots in the near future. Their direct bandgap properties and wide range of transparency as well as a bandgap offer a wide range of possibilities for interesting equipment.
