Insight into the Growth Mechanism of Mixed Phase CZTS and the Photocatalytic Performance

Nanomaterials, 2022
In this work, CZTS particles with a mixed phase of wurtzite and kesterite were synthesized by the solvothermal method. The time-dependent XRD patterns, Raman spectra, SEM, and EDS analysis were employed to study the growth mechanism of CZTS.

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)

X-Ray Spectrometry, EarlyView.
ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Ag‐Promoted Na Retention for Synergistic Defect Passivation in Kesterite Solar Cells

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
A synergistic Ag–Na codoping strategy in solution‐processed kesterite solar cells enables simultaneous lattice ordering and defect passivation. Ag promotes grain growth and Na retention, while Na enhances carrier concentration and reduces recombination.

Efficient Kesterite Solar Cells via Scalable Doctor‐Blading of 2‐Methoxyethanol‐Based Molecular Ink

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
A new record efficiency of 13.26% has been achieved for doctor‐bladed CZTSSe solar cells, fabricated for the first time from an MOE‐based molecular ink in ambient air. Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film solar cells have garnered significant interest owing to their appealing properties, such as earth‐abundant composition, environmental friendliness, high

Improvement of Structural and Optical Properties of V+‐Implanted CZTS Thin Films at Different Fluences

physica status solidi (a), Volume 223, Issue 12, 24 June 2026.
This study investigates the effects of vanadium ion implantation on pristine copper zinc tin sulphide (CZTS) thin films. The CZTS thin films were synthesized via a two‐stage process: electron beam deposition of metal precursors (Cu, Zn, and Sn) followed by sulphurization in a tube furnace at 500°C for 30 min.

Alternativa bakkontakter för CZTS tunnfilmssolceller [PDF]

, 2020
In this thesis, alternative back contacts for Cu2ZnSnS4 (CZTS) thin film solar cells were investigated. Back contacts for two different configurations were studied, namely traditional single-junction cells with opaque back contacts and transparent back ...

A coincidence‐based response matrix for correction of charge sharing spectral distortions in photon counting detectors

Medical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Charge sharing between pixels distorts the count and spectral information of X‐ray photon counting detectors. Compensation methods for charge sharing effects are required to exploit the full potentiality of these detectors in medical diagnosis.

Leakage currents and capacitances of thick CZT detectors [PDF]

2007 IEEE Nuclear Science Symposium Conference Record, 2007
The quality of Cadmium Zinc Telluride (CZT) detectors is steadily improving. For state of the art detectors, readout noise is thus becoming an increasingly important factor for the overall energy resolution. In this contribution, we present measurements and calculations of the dark currents and capacitances of 0.5 cm-thick CZT detectors contacted with ...

Role of Nitrogen Doping in Defect Control and Phase Stability of Sulfurized SnS Thin Films

physica status solidi (b), Volume 263, Issue 6, June 2026.
Nitrogen doping in SnS thin films influences defect formation and phase stability during sulfurization. Moderate N incorporation suppresses secondary phases and enhances carrier concentration at high temperatures. Carrier transport shifts from grain‐boundary‐limited to ionized‐impurity‐limited conduction, indicating activation of electrically active ...
