Because of its excellent opto-electronic properties, CdZnTe (CZT) has been the material choice for x- and gamma-ray detectors operable at room temperature. CZT is leading commercially available room-temperature radiation detector today. Although much progress made over past three decades, today's crystals still face certain challenges, especially presence performance-limiting materials defects ...

Abstract Cu 2 SrSnS 4 (CSTS) is a promising alternative candidate to ZnSnS (CZTS) for single- or multi-junction photovoltaics (PVs) owing its efficient light-absorbing capability, earth-abundant, nontoxic constituents, and suitable defect properties. However, as novel absorber material, several fundamental properties need be characterized before further progress can made in CSTS photovoltaics. ...

In this work, Cu/Zn/Sn-based ternary and quaternary chalcogenides inks were synthesized via hot injection and/or from ball-milled powders. The used to fabricate thermoelectric generators (TEGs) based on p-type chalcogenide n-type aluminum-doped zinc oxide (AZO) thin films spin-coating magnetron sputtering, respectively. This work highlights the first-ever attempt in a facile scalable method thi...

Field-Effect Passivation The implementation of Ga2O3 thin film effectively passivates the CZTS/TiO2 heterojunction by blocking holes away from buffer layer and acts as an electron-selective contact. This hole-blocking reduces interface recombination evident significant photoluminescence quenching. More information can be found in article number 2200001 Mukesh Kumar co-workers.

Monodisperse Cu2ZnSnS4 (CZTS) nanocrystals with tunable shape, crystalline phase, and composition are synthesized by efficient thermolysis of a single source precursor of mixed metal-oleate complexes in hot organic solvents with dissolved sulfur sources. Suitable tuning of the synthetic conditions and the Cu/(Zn + Sn) ratio of the precursor has enabled precise control of the crystalline phase i...

Introduction Dye-sensitized solar cells (DSSCs) are widely recognized as a promising alternative and cost-effective technology for solar-toelectric energy conversion. Current silicon solar cells are limited due to their lack of flexibility, high cost of manufacturing and installation, and heavy weight. Alternatively, dye-sensitized solar cells have a very simple fabrication process, low fabrica...
