Self‐Powered Broadband High‐Responsivity Photodetectors: p‐(CuS)x(ZnSe)1−x/p‐Si Isotype Heterojunction

Small, EarlyView.
This study reports a self‐powered broadband photodetector based on compositionally tuned p‐(CuS)x(ZnSe)1−x/p‐Si isotype heterojunctions. Increasing the CuS ratio improved the film crystallinity and produced a denser, more homogeneous nanopillar morphology, enhancing light absorption.

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

Advances in Thermoelectric Cu2ZnSnS4: From Structure, Synthesis to Performance

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Thermoelectric technology has the capacity to directly convert waste heat into electricity and vice versa. For a long time, Cu2ZnSnS4 (CZTS) has been extensively researched in the domains of solar cells and photocatalysis due to its exceptional photovoltaic properties, but its wide bandgap prevents it from being favored in thermoelectrics ...

Cation Distribution in Li2CaSiO4:Gd, Pr, Na Uncovered Through Anomalous Diffraction

European Journal of Inorganic Chemistry, Volume 29, Issue 20, 17 July 2026.
Li2CaSiO4 co‐doped with Gd3+ and Pr3+ shows strong blue‐to‐UV‐B up‐conversion. Herein, we explore the doping element distribution in order to discern the reason for the strongly supportive co‐doping effect using high‐resolution Rietveld refinement and multiple‐edge anomalous dispersion measurements.

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.
