What are CdTe solar panels?
Most solar panels today - and virtually all that are sold for residential use - are made with silicon solar cells.
Hundreds of millions of polycrystalline and monocrystalline silicon solar panels are manufactured annually. The economies of scale of this global manufacturing make it difficult for new technologies to break into the market, but one that has carved out a sizable market share is cadmium telluride.
Also referred to as CadTel or CdTe for the atomic symbols for cadmium and tellurium, this is a thin film solar technology.
