文摘
- •
A new synthesis procedure for CdS deposition by CBD has been demonstrated.
- •
In our new recipe, we have deposited 37 nm thin CdS layer on CZTSSe absorber.
- •
The device efficiency has shown improvement from 5.9% to 6.9%.
- •
EQE spectra show an improved charge collection in entire absorption spectrum.
