Optimization of Electronic Properties of Methylammonium Lead Bromide by Changing its Anionic Composition

   Chlorine-substituted crystals of methylammonium lead bromide MAPbBr_3–хCl_х, x = 0.01, …, 0.10, were synthesized. The effect of changing the anionic composition on their electrical properties was studied, and the optimal chlorine content was determined to achieve the desired conductivity characteristics. The electronic properties of MAPbBr_3–хCl_х were studied using impedance spectroscopy and optical absorption spectroscopy. High-resolution NMR (¹H) and powder X-ray diffraction were used to confirm the quality of the synthesis.
