Which risk increases because of cation vacancies in perovskite solar cell lattice?

💡 Explanation

Cation vacancies promote increased trap states at grain boundaries; therefore, charge carrier loss increases because non-radiative recombination at the grain boundaries occurs rather than efficient charge separation through the designed energy bands.
