Compositional Inhomogeneity of Multinary Semiconductor Nanoparticles: A Case Study of Cu2ZnSnS4

Probe-corrected scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy were used to characterize the inter- and intraparticle compositional inhomogeneity of multinary Cu2ZnSnS4 (CZTS) nanoparticles. CZTS nanoparticles were …

Synthesis of (CuInS2)0.5(ZnS)0.5 Alloy Nanocrystals and Their Use for the Fabrication of Solar Cells via Selenization

Kesterite Cu $_textrm2$ ZnSn(S,Se) $_textrm4$ Absorbers Converted from Metastable, Wurtzite-Derived Cu $_textrm2$ ZnSnS $_textrm4$ Nanoparticles

Wurtzite-derived copper−zinc−tin sulfide nanoparticle films were observed to undergo a phase transformation to a kesterite phase when exposed to Se vapor at 500 °C. The resulting dense and selenized Cu2ZnSn(S,Se)4 (CZTSSe) films were found to have the …
