In spite of the outstanding properties of metal halide perovskites, its polycrystallinenature induces a wide range of structural defects that results in charge losses thataffect thefinal device performance and stability. Herein, a surface treatment is usedto passivate interfacial vacancies and improve moisture tolerance. A functionalorganic molecule, phenylethyl ammonium iodide (PEAI) salt, is dissolved with theantisolvent step. The additive used at low concentration does not induce formationof low-dimensional perovskites species. Instead, the organic halide species pas-sivate the surface of the perovskite and grain boundaries, which results in aneffective passivation. For sake of generality, this facile solution-processed synthesiswas studied for halide perovskite with different compositions, the standardperovskite MAPbI3, and double cation perovskites, MA0.9Cs0.1PbI3andMA0.5FA0.5PbI3, increasing the average photoconversion efficiency compared tothe reference cell by 18%, 32%, and 4% respectively, observed for regular, n-i-p,and inverted, p-i-n, solar cell configurations. This analysis highlights the generalityof this approach for halide perovskite materials in order to reduce nonradiativerecombination as observed by impedance spectroscopy. [-]
