Initial oxidation of cuinse2
Webb2 mars 2024 · Atomic-scale oxidation dynamics of Cu 2 O nanocrystallines (NCs) are directly observed by in situ high-resolution transmission electron microscopy. A two-stage oxidation process is observed: (1) The initial oxidation stage is dominated by the dislocation-mediated oxidation behavior of Cu 2 O NCs via solid-solid transformations, … WebbThe creation of a suitable inorganic colloidal nanocrystal ink for use in a scalable coating process is a key step in the development of low-cost solar cells. Here, we present a facile solution synthesis of chalcopyrite CuInSe2 nanocrystals and demonstrate that inks based on these nanocrystals can be used to create simple solar cells, with our first cells …
