The major cause of instability of perovskite solar cells is believed to be ion migration. They claimed that perovskite solar cells have demonstrated limited operational lifetimes, primarily due to ...

Although local defects in chloride-iodide-based perovskite are hard to avoid due to ion migration, a group of scientists have now found a way to passivate them. They used different combinations of ...

Perovskite is subject to ion migration — the movement of ions within the crystal lattice. When exposed to heat and light, electric fields from solar cell components cause ions within the ...

“NH2 nucleophilic sites in 4PTSC hinder SnI2 oxidation and ion migration, while its π-conjugated ... Engineering for Wide-Bandgap Sn Halide Perovskite Solar Cells with a Record Efficiency ...
