“…The absorption coefficients of all the structures are very high (over 10 4 cm −1 ) in the shorter wavelength region, making them ideal for numerous OE applications. However, the absorption coefficient is comparatively less than both theoretically and experimentally observed MAPI perovskites [35–37] . The absorbance nature of HBPI0 is analogous to previous research [9,14] .…”

Organometallic perovskites have become one of the most common multifunctional materials in optoelectronic research fields. This research studies density functional theory calculation on orthorhombic hydrazinium lead iodide (N2H5PbI3) perovskite by replacing A‐site cation with a borane ammonium (BH2NH3+) ion. The perovskite showed a significant structural deformation and an orthorhombic to triclinic phase transition due to A‐site ion replacement. The N2H5PbI3 perovskite has a band gap of 1.64 eV, suitable for the solar cell absorber layer. The band gap has increased to 2.12 eV after complete A‐site ion replacement. All structures showed a high absorption coefficient over 104 cm−1 in the low wavelength region and an increase in refractive index from 2.5 to 2.75 due to ion replacement. All the structures showed high optical conductivity of 1015 s−1 order in the blue wavelength region. These new perovskite structures hold the potential to provide a revolution in optoelectronic research.

“…HAPI showed an extremely strong AC (over 10 4 cm −1 ) in the shorter wavelength of the visible region, making them perfect for various OE applications [ [43] , [44] , [45] , [46] ], e.g., LASER, solar cells, LED, etc. However, the AC is comparatively lower than the MAPI perovskites observed in theoretical and practical studies [ [47] , [48] , [49] ]. The absorption curve is analogous to previous research [ 24 ].…”
