Influence of Film Thickness on Screen‐Printed BiFeO3 Photoelectrodes for Nitrogen Reduction Reaction

Nano Select, Volume 7, Issue 3, March 2026.
Influence of film thickness on screen‐printed BiFeO3‐photoelectrodes for nitrogen reduction reaction. Optimization of BiFeO3‐based photoelectrodes film thickness for nitrogen conversion into ammonia by photo‐electrochemical cell. After 1 h of PEC reaction, a faradic efficiency close to 90% for ammonia at ‐0.4 V versus NHE is obtained.

Defect Properties of Na and K in Cu2ZnSnS4 from Hybrid Functional Calculation

, 2017
In-growth or post-deposition treatment of $Cu_{2}ZnSnS_{4}$ (CZTS) absorber layer had led to improved photovoltaic efficiency, however, the underlying physical mechanism of such improvements are less studied. In this study, the thermodynamics of Na and K

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

Progress 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 ...

Cu2ZnSnS4 thin film solar cells grown by fast thermal evaporation and thermal treatment [PDF]

, 2018
Cu2ZnSnS4 thin films have been produced via rapid thermal evaporation of off-stoichiometric kesterite powder followed by annealing in an Ar atmosphere. Different heating rates were applied during the thermal treatments.

Device Postannealing with Superficially Ag‐Modified Absorber for High‐Efficiency Cd‐Free Cu2ZnSnS4 Solar Cells

Small Science, Volume 6, Issue 2, February 2026.
A superficial Ag‐modification process using spin‐coated Ag2ZnSnS4 layer on presulfurized CZTS precursor is proposed to improve the surface defect properties. The absorber fabrication process reduces the interfacial nonradiative recombination loss and suppresses the generation of deep defects during device annealing, enabling 10.53% efficient Cd‐free ...
