Effect of Al2O3 Dot Patterning on CZTSSe Solar Cell Characteristics
Nanomaterials, 2020 In this study, a 5-nm thick Al2O3 layer was patterned onto the Mo electrode in the form of a dot to produce a local rear contact, which looked at the effects of this contact structure on Cu2ZnSn(S1-xSex)4 (CZTSSe) growth and solar cell devices.

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 ...
