Exploring the structural, morphological, optical and magnetic properties of pure and Ni-doped Triple Perovskite La2SrFe2TiO9 for magneto-opto electronic applications

Enhancing the structural and optoelectronic properties of double ETL nickel-doped CsPbIBr2 perovskite solar cells

“…Specifically, substituting Pb 2+ ions with Ni 2+ in the lattice is hypothesized to introduce new electronic states that could facilitate more efficient charge transport and collection. 15 Furthermore, the smaller ionic radius of Ni 2+ compared to that of Pb 2+ might result in a more densely packed crystal structure, potentially enhancing the material's stability and durability. 16 These improvements are critical for advancing the performance of perovskite solar cells, ultimately contributing to the development of more efficient, stable, and environmentally friendly photovoltaic technologies.…”
