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.

Crystal structure and electronic structure of quaternary semiconductors Cu$_2$ZnTiSe$_4$ and Cu$_2$ZnTiS$_4$ for solar cell absorber

, 2012
We design two new I2-II-IV-VI4 quaternary semiconductors Cu$_2$ZnTiSe$_4$ and Cu$_2$ZnTiS$_4$, and systematically study the crystal and electronic structure by employing first-principles electronic structure calculations.

The synthesis and characterization of Cu2ZnSnS4 thin films from melt reactions using xanthate precursors [PDF]

, 2017
Kesterite, Cu2ZnSnS4 (CZTS), is a promising absorber layer for use in photovoltaic cells. We report the use of copper, zinc and tin xanthates in melt reactions to produce Cu2ZnSnS4 (CZTS) thin films.

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 ...

Standard enthalpy of formation kesterite Cu2ZnSnS4

Геохимия, 2019
The standard enthalpy of kesterite formation (Cu2ZnSnS4) is calculated from the calorimetric determinations of the enthalpy of its formation from simple sulphides: 2CuS + ZnS + SnS → Cu2ZnSnS4 using literature data on the standard enthalpies of the formation of simple sulphides.

Investigating synthesis of Cu2ZnSn(Se1-x,Sx)4 for values of 0≤x≤1 by S for Se substitution and direct sulphidisation of metallic precursors [PDF]

, 2011
Thin layers of Cu2ZnSn(Se1-x,Sx)4 were produced by selenisation and subsequent sulphur substitution of DC sputter-deposited metallic CZT precursors on soda-lime glass. Values of x=(0, 0.07, 0.12, 0.17, 0.28, 1) were measured by EDS.

Electronic structure and transport properties of Cu-deficient kuramite Cu3-xSnS4

, 2015
Electrical and thermal transport properties of Cu-deficient kuramite Cu3-xSnS4 (CTS) was examined as a possible earth-abundant thermoelectric material. Crystallographic structure of CTS was characterized by partial disorder between Cu and Sn. In contrast
