Abstract

Herein, we investigate morphology, structure and optical properties of low band gap organic-inorganic halide perovskite based on a mixture of lead and tin as the divalent cation in ABX3 structure. A significant change in morphology of CH3NH3SnxPb1−xI3 perovskite with x as well as an alteration in crystal structure from I4cm (β-phase) to pseudocubic P4mm (α-phase) space groups is observed when Sn is the dominant divalent cation (x ≥ 0.5). Photo thermal defection optical absorption spectroscopy (PDS) and photoluminescence (PL) of CH3NH3SnxPb1−xI3 show the non-linear change in the band edge of perovskite. The bandgap as low as 1.17 eV and the most red-shifted PL at 1035nm is achieved for perovskite with x=0.8. In addition, higher electronic disorder is measured for CH3NH3SnxPb1−xI3 compounds with higher x.
