All‐inorganic CsPbI 2 Br perovskite acquires affirmation in recent years by reason of the excellent balance between stability and power conversion efficiency (PCE), but its PCE is still inferior to commercial application standard, which inferiority roots from uncontrolled crystallization a mass imperfections. Herein, regulated introducing certain amount lead acetate into precursor, complex Pb(Ac) × DMSO PbI forms precursor. The Oswald crystal pattern changes 2D layered structure —3D cubic...
The subsurface of perovskite (PVK) triggers non-radiative recombination and initiates film degradation due to the impurities defects. This study investigates limitations conventional surface post-treatment proposes an innovative pre-treatment strategy achieve complete impurity elimination defect passivation subsurface. considerable activity unannealed PVK films provides a sufficient basis for effective modification. Following pre-treatment, cadmium ions (Cd
