Abstract
The perovskite structure is decomposed to its precursor in the face of continuous light irradiation (mainly UV light), humidity, and heat. In this work, mesoporous PSCs are fabricated in uncontrolled environment. The UV light stability of the PSC is enhanced by adding a photoactive phase change material (PCM) into the perovskite. The PCM undergoes trans to cis isomerization under UV light irradiation. Then, the cis form absorbs the heat produced in the solar cell and converts it into its trans isomer in a reversible process. By this approach, the destructive effect of UV light and heat is prohibited, leading to the enhancement of PSC durability by more than 138 % compared to devices without PCM. It should be noted that there is no significant difference in the PCE of both solar cells.
