## Description

- description: "The Power conversion efficiency (PCE) of Perovskite solar cells (PSCs)
    declines during operation with time. The cause of deterioration of perovskite
    solar cells is the instability of the perovskite crystal is induced by external
    factors, including humid air, heat, light, and electric field1,2. Perovskite solar
    cell research has advanced with analytical models describing cell operation and
    non-uniform generation3. Impedance spectroscopy of perovskite solar cells is used
    to study the charge transport mechanism, electrical properties, and degradation
    of PSCs4.\r\nTo understand the degradation a simulation based on analytical and
    numerical model is performed. In analytical model-based simulation the degradation
    is considered as the function of surface recombination velocity. While in numerical
    simulation based on drift diffusion model the degradation is considered as the
    function of ion density.\r\nIt is found that the surface recombination leads to
    charge carrier loss, accelerating cell degradation over time and with temperature.
    Impedance spectra show that higher-frequency components play a larger role in
    degraded solar cells. Low ion density minimizes low-frequency contributions in
    impedance spectra. Impedance changes reveal how ion density impacts charge transport
    and recombination in PSCs."
