Abstract

original image

CZTS: Atlanta. A supercritical CO2 continuous-flow reactor is employed to deposit micro- and nanoparticles of copper zinc tin sulfide (CZTS), a promising material for thin-film solar cells, onto a silicon wafer. The image shows a chemical map of deposited CZTS particles (scale bar: 15 μm), and a Raman spectrum with a peak characteristic of CZTS.
