Excited to share my research work on optoelectronic kesterite materials using solid-state multinuclear magnetic resonance spectroscopy at the global NMR twitter conference #GlobalnmrTC2022 #energy #material #structure @MichaelisNMR pic.twitter.com/YHvozb63zM

Solid-state NMR spectroscopy is used to delve into the local structural variation in photovoltaic Cu2Zn1–xCdxSnS4 materials and their conversion to a stannite phase upon critical Cd-loading. 113Cd NMR spectroscopy reveals the coexistence of stannite and kesterite. 63Cu NMR data combined with DFT computations resolve the conundrum of Cu/Zn disorder.
