At the interface between the perovskite solar cell and the LIB, an electrolyte or electrolyte medium is present, allowing the migration of lithium ions. During the charging and discharging process, this lithiation alters the perovskite, as the Li + embeds itself in the interlayer spacing between the octahedrons and [PbI 6] 4−.
Materials made of perovskites are prone to deterioration when interacting with environmental effects including, light, oxygen, moisture, and heat . Over time, this deterioration may cause the solar cell's performance and efficiency to decrease, which would ultimately affect the solar cell's long-term dependability and durability .
