Mixed halide perovskites are gaining attention in solar energy research due to their high efficiency and potential for cost-effective, scalable technology.
Light soaking, or exposing materials to sunlight, helps reduce harmful non-radiative recombination and optimizes performance in these perovskite films.
Our study shows that while short light exposure (up to 1 hour) enhances optoelectronic properties, prolonged exposure (5 hours) causes issues like phase segregation and decreased charge mobility.
