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