## Description

- description: 'Investigating the degradation mechanisms of perovskite solar cells
    (PSCs) is paramount to addressing stability-related issues. Our study delves into　the
    deterioration of PSC by probing thermal hysteresis of photocurrent (THPC) and
    thermally active ionic dynamics. THPC emission reveals alterations influenced
    by interfacial ionic or charge accumulation. Photogenerated current exhibits a
    significantly higher degree of variation in degraded devices with a wide range
    of ionic charge densities. This highlights the substantial influence of thermally
    active ionic charge on PSC performance degradation, particularly in devices with
    lower photocurrent. This study highlights the direct correlation between the degradation
    of PSC devices and the presence of thermally activated charges. '
