Nanostructure conversion and enhanced photoluminescence of vacancy engineered substoichiometric tungsten oxide nanomaterials

B. B. Wang et al.

Summary: The solvothermal synthesis method successfully controlled the morphology and structure of WO3-x nanomaterials. The study on the photoluminescence properties revealed emissions in ultraviolet, blue, green, and red, with the intensity enhancement attributed to factors like increased oxygen vacancies and nanocavity structures. These results offer a new technique for structure control and potential applications in catalysis fields, contributing to the development of next-generation nanodevices and catalytic materials.

The impact of Kelvin probe force microscopy operation modes and environment on grain boundary band bending in perovskite and Cu(In,Ga)Se2 solar cells

Evandro Martin Lanzoni et al.

Summary: Research shows that measurements of workfunction in typical solar cell absorbers may exhibit artifacts, and exposure to air can alter the contrast of grain boundaries and facets, leading to incorrect interpretations of grain boundary physics. Frequency modulation (FM)-KPFM measurements on absorbers not exposed to air demonstrate minimal band bending at grain boundaries, with facet-related contrast dominating the electronic landscape of the semiconductor surface due to the polycrystalline nature of the absorbers.

Effects of oxygen concentration variation on the structural and optical properties of reactive sputtered WOx thin film

Samiya Mahjabin et al.

Summary: The study investigates the influence of oxygen concentration on the structural and optical properties of WOx films, prepared by reactive sputtering at varying oxygen concentrations. The films' thickness and surface roughness were found to be dependent on oxygen concentration, impacting their optical parameters. The optimized WOx film shows potential as an efficient electron transport layer for perovskite solar cells, achieving high quantum efficiency and short-circuit current density.
