Structural modifications in Cs2AgBiBr6 induced by methylammonium substitution: Insights from X-ray diffraction and X-ray absorption fine structure

Lead-free double perovskites such as Cs₂AgBiBr₆ are promising for sustainable optoelectronics, yet their structural rigidity and limited defect tolerance constrain further optimisation. This study examines the structural evolution of Cs2AgBiBr6 under methylammonium (MA+) substitution to clarify its...
