Organic-inorganic hybrid double perovskites have attracted increasinginterest in the commercialization of lead-free and nontoxic perovskites due totheir unique optoelectronic properties compared with inorganic perovskites. Inthis study, the structural, electronic, optical and properties of 3 Pb-freecompounds (CsMA)NaBiX$_6$ (MA= methylammonium; X= Cl, Br, I) were simulatedusing first-principles density functional theory (DFT). Results show that theinvestigated compounds are semiconductors with tunable bandgaps characteristicsthat can be used in devices like light emitting diodes, and predict thesuitability of the (CsMA)NaBiI$_6$ organic-inorganic hybrid double perovskitein this study for optoelectronic applications owing to its high absorptioncoefficient (in the order of $10^6$cm$^{-1}$), dielectric constant ($\approx3.24$), and refractive index (2.50) as well as its stability as revealed by itshigh formation energy. Additionally, the high absorption coefficient, highrefractive indices and dielectric constants of the investigated materialsposits that they have a number of optoelectronic applications includingphotovoltaic cells among others.
