Tailoring in-gap states for optimizing the band gap in mixed-valent bromometallates, towards lead-free photovoltaics
{{output}}
Motivated by the task to replace toxic lead halide perovskites with lead-free environmentally benign light-harvesting materials for photovoltaics, we have synthesized two new hybrid bromometallates, (AH2)4[Sb2Br10(SbBr6)2(Br)2] (1) and (AH2)2[(BiBr6)(SbBr6)]·... ...
