2. Polycrystalline chalcogenide systems
In the polycrystalline sector, two options have clearly stood out in recent years for their performance and ease of implementation: the CdTe sector and the CuInSe 2 sector (and its Cu(In,Ga)Se 2 variant, also known as CIGS), both of which are most often combined with a CdS window layer.
As we shall see, the performance of polycrystalline materials is closely linked to grain size and orientation. The type of conduction is generally governed by the chemical composition, in particular the deviation from stoichiometry, which means that layer doping is often unnecessary.
2.1 CdS/CdTe
Until recently, it was accepted that the CdS/CdTe pathway represented...

CdTe
A number of process-related issues remain to be resolved.
CdTe doping is still not well controlled. Empirically, we've found that treatment with CdCl 2 (a compound well known for helping the recrystallization of CdS layers) is beneficial. All at once, it activates the junction, passive grains,...
