Multinuclear (67Zn, 119Sn and 65Cu) NMR spectroscopy – an ideal technique to probe the cationic ordering in Cu2ZnSnS4 photovoltaic materials†
Abstract
For the very first time, 67Zn, 119Sn and 65Cu NMR investigations have been carried out on Cu2ZnSnS4 derivatives (CZTS) for photovoltaic applications.
