Does ISET use Cadmium in its CIGS modules?
Presently, ISET uses cadmium only in the Cadmium Sulfide buffer layer of the CIGS cells. This layer is less than 0.1 µm thick and contributes to the collection of electric charge within the solar cell. ISET is currently investigating methods for eliminating cadmium use entirely, and has confidence that this can be achieved in the near term without impacting the high quality and performance of our CIGS modules.
