“…RbSnX 3 (X = I, Br, Cl) PVSKs exhibit a peak in the visible region with magnitudes of 5.3, 3.7, and 3.1 at energies of 2.2, 2.8, and 3.3 eV, respectively. Another important quantity, termed the complex refractive index η ∼ false( ω false) of the material, can be expressed as: η ∼ false( ω false) = n 1 false( ω false) + i k 2 false( ω false) = false( ε 1 + i ε 2 false) 1 / 2 where n 1 (ω) and k 2 (ω) are the real and imaginary components of n ∼ false( ω false) . Additionally, n 1 (ω) and k 2 (ω) can be accomplished with the component of ε(ω) as n false( ω false) = true[ ε 1 ( ω ) 2 + ε 1 ( ω ) + i ε 2 ( ω ) 2 true] 1 / 2 …”

Molecular engineering of inorganic halide perovskites and HTMs for photovoltaic applications

“…Inorganic metal halide perovskites having monovalent inorganic cations such as sodium and cesium at A position have received great interest due to their suitable chemical and thermal stability, and high mechanical strength [28,29]. A theoretical study has been applied to a set of inorganic metal halide perovskites with a structural formula of ABX 3 that Cs, Rb, and Tl were known as A, Pb, Sn, and Ge as B, and Br, Cl, I as X [30].…”
