Simultaneous Defect Passivation and Crystallization Kinetics Regulation of Perovskite Thin Films Using a Nitro-Rich Additive for Efficient Inverted Solar Cells.
Metal halide perovskite solar cells are fundamentally limited by uncontrollable crystallization kinetics during film formation and defect-induced non-radiative recombination. To address this challenge, 4-Chloro-3,5-dinitrobenzotrifluoride (CNBF) is designed and introduced to simultaneously achieve precise regulation of...
