Bulk passivation and suppressing non-radiative recombination loss in 3D all-inorganic CsPbIBr2 perovskite solar cell via 2D layered perovskite framework

Improving perovskite film quality for reducing the non-radiative recombination centers is one of the key aspects of designing efficient and stable perovskite solar cells (PSCs). In this work, we fabricated...
