- •
CdS thin films synthesized by changing the complexing agents, the Cd source and the nominal S/Cd ratio are investigated.
- •
CdS:Cu showed an efficiency improvement in CIGSe solar cell in comparison with the non-doped one.
- •
By using Cd(NO3)2 as Cd source in CdS deposition, an 8.03% CZTSe solar cell efficiency was achieved.
- •
Higher Voc values are obtained for thinner and more resistive CdS layers.
- •
It is demonstrated that CdS/CIGSe and CdS/CZTSe solar cells operate rather as a MIS structure.
