Silicon/chlorine doping and co-doping suppress nonradiative charge recombination of Cs2SnBr6

Key Points

• Doping with silicon and chlorine significantly lowers nonradiative charge recombination rates.
• The study shows up to a 30% reduction in charge loss due to recombination under specific conditions.
• Observational analysis focuses on cesium tin bromide, highlighting the impact of dopants on material performance.
• This finding suggests enhanced capabilities for Cs2SnBr6 in optoelectronic applications, increasing its practical utility.
