## Description

- description: The inorganic carrier transport layers are robust and stable to the
    environment compared to the organic hole transport layer (HTL). Here, we report
    on the fabrication of the halide perovskite solar cells (HaPSCs) employing CuI
    deposited with ammoniated aqueous solution ink as HTL and explored the material
    properties and device characteristics. The film morphology of CuI is found to
    have an influence on the HaP film growth and hence effects on the device parameters.
    The HaPSC with CuI has demonstrated the power conversion efficiency of ~14.21%
    with high reproducibility. The capacitance spectra analysis shows that the deep
    trap states are induced in the perovskite absorber layer. The results obtained
    from the temperature-dependent open circuit voltage implicates that the recombination
    activities in the perovskite bulk are dominant. Furthermore, the HaPSC with CuI
    has revealed better air stability compared to the device with PEDOT:PSS. This
    work suggests that the CuI processed with aqueous precursor is a promising alternative
    HTL to PEDOT:PSS for efficient and stable perovskite solar cells as well as in
    a tandem device.
