In this study, a hydrothermal method was used to synthesize Tix MnNiO nanostructures for photovoltaic applications. The synthesized films display a hexagonal phase and are polycrystalline. They exhibit a preferred alignment on the (111), (112), (116), (121), and (200) planes. The angles 2 theta are (26.612, 30.816, 32.154, 33.154, and 37.856) degrees. The structural properties of the material are enhanced by incorporating titanium into the lattice of manganese, nickel oxide. By integrating titanium into the MnNiO lattice, the material's UV absorbance was enhanced. At 310 nm, the noticeable peaks of the materials show a rise in titanium concentration, leading to enhanced absorbance during synthesis. The material absorbance decreases as the wavelength of light in the visible region increases. The indirect bandgap energy of the synthesized Tix MnNiO film decreases with increasing molar concentration, ranging from 2.75 eV to 1.82-1.50 eV.

Recent successes in the development of lead (Pb) halide perovskites have urged extensive research into cost-effective photovoltaic devices, to avoid significant challenges related to stability and toxicity. In this study, device modeling was presented for lead (Pb)-free perovskite solar cells (PSC), by employing FAsnI3 as the perovskite absorber layer. The simulation evaluates the impact of varying thickness, acceptor density of the hole transport layer (HTL), and temperature within the ranges from 50 to 250 nm, 1x1018 cm-3 to 1x1022 cm-3, and 300 K to 450 K, respectively. The photovoltaic cell has inverted geometry (p-i-n) and device structure is ITO/PEDOT:PSS/FASnI3/BCP/Au. The FASnI3-based PSC exhibits an efficiency of 14.03%, current density (Jsc) 20.4 mA/cm2, fill factor (FF) 76.7%, and open circuit voltage (Voc) 0.92 V and these results are already presented experimental with same device structure. These results showed that a more eco-friendly solar cell using methyl ammonium tin was created successfully as perovskite. It is suggested to use alternative materials instead of methyl ammonium tin as perovskite.
