Self-Alignment of Bottom CZTSSe by Patterning of an Al₂O₃ Intermediate Layer

Nanomaterials, 2019
When CZTSSe is synthesized using a metal precursor, large voids of nonuniform size form at Mo back contact side. Herein, we demonstrate that the voids and CZTSSe in the lower part of the CZTSSe double layer can be controlled by using an Al2O3-patterned ...
