説明:

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.
