Developed the synthesis of CsSnI3 lead-free halide perovskite nanoplates while developing understanding of the stability of CsSnI3
Significance and Impact
This approach advances the understanding of the synthesis and the management of instability and defects in CsSnI3
- First synthesis of strongly quantum confined CsSnI3 nanoplates was achieved by hot-injection in Sn-rich conditions
- Ab initio calculations (GGA-PBE) highlight that synthesizing and processing CsSnI3 in Sn-rich conditions can reduce defect density and increase stability
- Experimentally, treatment with Sn-rich conditions increases carrier lifetime.
