Chalcogenide Letters is published monthly (12 issues per year), covering a wide range of fundamental and applied research in the field of chalcogenide materials. The journal is open to letters, short communications and breakings news inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in structure, properties and applications, as well as those covering special properties in nano-structured chalcogenides are admitted. Papers based on chalcogenide advanced nanomaterials with possible applications in electronics, optoelectronics, and photonics are encouraged. Also, articles on alternative and renewable energy sources in the field of chalcogenides are accepted for submission. Cross-fertilization of both crystalline and amorphous field in this special class of materials is one of the purposes of this Journal.

Abstract In this work, spin-coated Cu2ZnSnS4 (CZTS) thin films with systematically varied thicknesses were investigated to understand their influence on structural, compositional, and optical properties relevant to high-performance photovoltaic applications. CZTS absorber layers were fabricated using a sol-gel spin-coating technique, which offers simplicity, low cost, and excellent thickness control, followed by annealing at 450°C under a nitrogen atmosphere to promote crystallization and phase formation. X-ray diffraction (XRD) analysis revealed that films with a thickness of approximately 608 nm exhibited the highest crystallinity and a preferred orientation along the (112) plane, indicating enhanced structural order and improved grain… More >

Abstract In this study, a novel double-heterojunction perovskite solar cell (DHPSC) with the following structure: FTO/ZnO/CH3NH3PbI3−xClx/CH3NH3SnI3/p++ZnTe/Au was designed. It was optimized using the wxAMPS simulation software. A systematic parametric analysis was performed to investigate the influence of electron transport layer (ETL) ZnO and hole transport layer (HTL) thicknesses on photovoltaic performance. That includes short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF), and power conversion efficiency (η). The results indicate that once a minimum ZnO thickness is achieved, further increases have a negligible effect on performance. Whereas variations in ZnTe thickness markedly influence Voc and η. The optimal configuration More >

Abstract A sulfate–chloride electrolyte was used to deposit alloy layers on AISI 1018 coupons while co-introducing ZnS nanoparticles (5–20 g/L) to tune microstructure and durability under combined saline exposure and dry sliding. Cross-sectional SEM confirmed continuous deposits of ~24–26 μm, and XRD indicated γ-phase dominance with pronounced grain refinement: crystallite size decreased from 42 ± 3 nm (particle-free) to 28 ± 2 nm at 15 g/L. In 3.5 wt% NaCl, polarization data showed a progressive ennoblement of Ecorr from −1.032 to −0.981 V (vs. SCE) together with a reduction of icorr from 8.47 to 1.82 μA/cm2 at 15… More >

Abstract Doping the absorber layer is a critical process for enhancing the performance of polycrystalline CdSeTe solar cells. Replacing traditional Cu doping with Group V dopants offers a pathway to fabricate devices with improved efficiency and stability. However, the dopant activation rate in polycrystalline structures remains low, typically only a few percent. While rapid thermal annealing (RTA) has been successfully employed to achieve high activation rates in single-crystal CdTe devices, its application to polycrystalline CdSeTe solar cells has been scarcely reported. In this study, we systematically applied multi-step annealing to investigate the dopant activation of in-situ As-doped More >

Abstract In this study, zinc sulfide nanoparticles (ZnS NPs) and zinc sulfide @ Silver sulfide core-shells (ZnS@Ag2S NPs) were prepared using the green method with mint leaf extract as a reducing and coating agent, at varying concentrations of silver nitrate (AgNO3) (0.005, 0.01, and 0.02 M). X-ray diffraction analysis (XRD) results showed the formation of a cubic phase of ZnS NPs and a monoclinic phase of Ag2S with increasing silver nitrate concentration. The average crystalline size of ZnS NPs was calculated to be 2.01 nm and (2.78, 2.65, and 2.13 nm) after Ag2S formation, while the shell (Ag2S) was… More >

Abstract The increasing depletion of fossil fuels and the escalation of global temperatures have intensified the need for sustainable energy sources such as solar power. Copper Zinc Sulphide (CuZnS) is a potential absorber for solar cells. This study reports the structure and composition of annealed CuZnS samples using X-ray Photoelectron Spectroscopy (XPS) analysis technique. CuZnS thin films prepared using low-cost chemical bath deposition (CBD) technique are annealed at 100°C, 200°C, and 300°C. The samples are analysed using Energy Dispersive X-ray Spectroscopy (EDX), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), UV Visible NIR spectroscopy (UV-VIS) and Hall… More >

Abstract We present a systematic investigation of FeS2 thin films deposited by ultrasonic spray pyrolysis (USP) at different deposition times (15–40 min), with the aim of understanding their structural, optical, and electrical evolution and their suitability for heterojunction device applications. Particular attention is given to the integration of the optimized FeS2 layer with a Co-doped SnS2 bottom layer to form a p–n heterojunction. Structural analysis by X-ray diffraction reveals a transition from an amorphous/oxidized phase at short deposition times toward well-crystallized pyrite after 25 min, while the 40-min film exhibits the most intense reflections and the largest crystallite… More >
