## Description

- description: "Understanding the degradation mechanisms in perovskite solar cells
    (PSCs) is critical to addressing their stability challenges and ensuring their
    reliability for long-term applications.1,2 Among the various performance issues,
    photocurrent loss is a prominent indicator of degradation in PSCs, directly impacting
    their efficiency and operational lifespan.3,4 This study investigates the underlying
    processes contributing to degradation, focusing on the thermal hysteresis of photocurrent
    (THPC) and the role of thermally activated ionic and recombination dynamics.5
    THPC in degraded devices reveals a significantly higher variation in photogenerated
    current compared to pristine devices. \r\nCapacitance analysis supports the role
    of interfacial ionic charges and active defects in the degradation process.6,7
    Degraded devices exhibit increased capacitance, which corresponds to the presence
    of localized ionic charges and defects at critical interfaces. These ionic charges
    create localized electric fields, which intensify recombination losses and hinder
    efficient charge transport within the device.8 The interplay of these effects
    exacerbates the degradation of PSCs under operational conditions. The simulations
    confirm that these interfacial defects are particularly detrimental in the presence
    of thermally activated ionic processes, which amplify their negative effects under
    prolonged thermal and photonic exposure. This study highlights the strong connection
    between PSC degradation and the presence of thermally activated traps and interfacial
    charge accumulation, emphasizing the critical need to passivate these pathways
    to enhance device stability."
