Perovskite solar cells (MAPbI2Br or CH3NH3I2Br) are the subject of this thorough examination their optical, structural, and photovoltaic properties. These MAPbI2Br were prepared by sol–gel spin-coating process to make films both undoped Mn2+-doped materials. In addition, band gap energy (Eg) exhibited a steady downward trend as doping levels increased. The largest drop was observed at 4 % Mn2+ doping, when UV–Vis spectroscopy measured an Eg value 1.88 eV. This decrease in is essential improving MAPbI2Br's functionality. Furthermore, compared that used pure perovskite cells, efficiency manufactured shown significant improvement. Analyzing current–voltage (J-V) characteristics revealed produced with film had dramatically improved showed open-circuit voltage 1.02, fill factor 0.74, short-circuit current density 8.10 mA/cm2, impressive power conversion 6.14 %.

This study focuses on the investigation of beryllium (Be) doping in V2O5 nanoparticles and coordinated effects it has structural, optical, photocatalytic characteristics material. XRD analysis reveals modifications orthorhombic structure upon Be doping, decreasing crystallite size (68.7–46.6 nm), increased dislocation line density. Optimizing charge carrier mobility separation is crucial for improving activity, this achieved via these adjustments. Raman spectra indicated crystallinity with doping. The optical demonstrated an adjustable band gap (2.47–2.60 eV) reduced refractive index (2.49–2.45), that enhance light absorption efficiency. More importantly, shows Be-doped have better activity breakdown methylene blue, indicating its potential environmentally friendly remediation. present work contributes to advancement customized approaches maximizing functioning across a range applications by clarifying complex impacts
