## Description

- description: We analyzed and compared quantitatively the optoelectronic characteristics
    of perovskite PV devices with and without annealing the perovskite layer in a
    methyl ammonium chloride vapor atmosphere (MACl treatment). We found that the
    MACl treatment resulted in the mitigation of defect states, reduced defect density,
    improvement in the carrier profile, and passivation of recombination activities,
    which we infer as natural consequences of significantly improved film quality
    with better crystallinity and grain morphology of the perovskite layer. MACl-treated
    devices are more efficient with the best efficiency of ∼15.1% with small standard
    deviation (std.) (0.50%) and improved stability compared to devices without MACl
    treatment having the best efficiency of 12.4% with std. of 0.66%.
