Trivalent Ni oxidation controlled through regulating lithium content to minimize perovskite interfacial recombination
文献摘要:
Organic-inorganic hybrid perovskite solar cells,one of the most promising photovoltaic devices,have made great progress in their efficiency and preparation technol-ogy.In this study,uniform,highly conductive LinNiOx (0≤ n ≤ 1;0< x ≤ 3) films were prepared by electrochem-ical deposition for a range of Li concentration.Photo-voltaic performance for the perovskite solar cells was enhanced through incorporation of the ion pair of Ni3+(-) Ni2+ as the interfacial passivation.Depending on the amount of lithium doping,controlled interfacial oxidation was induced by Ni3+.The Li0.32NiOx inhibited charge recombination,reduced the defect density,and enhanced the photocurrent density.A maximum power conversion efficiency of 20.44% was obtained by Li0.32NiOx.Further,in the long-term,in-air stabilities of unencapsulated Lin-NiOx perovskite solar cells were demonstrated.
