Impact of Ce doping on the optoelectronic and structural properties of a CsPbIBr2 perovskite solar cell

“…This substitution, discussed in this paper, allows Ce to enhance the material's properties, including the crystal size, lattice parameters, and optical characteristics. 32,33 The use of Ce doping in perovskite materials allows for the adjustment of their bandgaps, which determine the range of wavelengths of light that they can absorb. By doping with Ce, the bandgap can be customized for specific applications, making cerium-doped perovskites suitable for a variety of optoelectronic devices, including LEDs and solar cells.…”
