Metastable defect response in CZTSSe from admittance spectroscopy

open access: yesApplied Physics Letters, 2017
Admittance spectroscopy is a useful tool used to study defects in semiconductor materials. However, metastable defect responses in non-ideal semiconductors can greatly impact the measurement and therefore the interpretation of results. Here, admittance spectroscopy was performed on Cu2ZnSn(S,Se)4 where metastable defect response is illustrated due to ...

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

DFT Modeling and Impedance Spectroscopy Analysis of a High Performance Zirconia‐Based Solar Cell

open access: yesNano Select, Volume 7, Issue 3, March 2026.
p‐SnS/n‐CdS heterojunction solar cells with Al‐ZnO/i‐ZnO window layers simulated using SCAPS‐1D and impedance spectroscopy enabled tracking of solar cell parameters. The optimal performance (η = 22.76%, Voc = 0.77 V) was achieved with a 5 µm SnS absorber at Rs = 1Ω.cm−2 and Rsh = 10 kΩ.cm−2.

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 271-285, March 2026.
We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...
