Here, a new promising perovskite structure of KMnF3 has been fabricated and characterized, which yields bandgap of 1.6 eV with fascinating moisture-resistance and phase stability. Investigation of structural, optical, stability and transport properties have done by XRD, SEM, UV–vis–NIR spectroscopy, photoluminescence and electrical conductivity test. Such examination indicated the high carrier mobility (18 cm2/V s) and density (1014/cm3) even after a long interval between each excitation. These transport properties are comparable to that of the organic perovskite, indicating the importance of KMnF3 for solar device applications.
