During the manufacture of a CIGS device, the metal back contact is deposited first, while in the case of the
CdTe solar cells, the back contact is deposited in the last processing step. What are the configurations of both
cells?
Both the CI(G)S and CdTe solar cells are made in a superstrate structure.
The CI(G)S solar cell is made in a superstrate structure, whereas the CdTe solar cell is made in a
substrate structure.
The CI(G)S solar cell is made in a substrate structure, whereas the CdTe solar cell is made in a
superstrate structure.
Both CI(G)S and CdTe solar cells are made in a substrate structure.
In a CdTe solar cell …
… light is mainly absorbed in the n-type CdS layer; this layer makes a junction with the p-type CdTe
layer.
