Shedding light on the environmental impact of the decomposition ofperovskite solar cell

Perovskite materials, as the heart of perovskite solar cells, attracted great interest in thephotovoltaic community since the efficiency of perovskite solar cells (PSC) dramatically increasedto over ۲۵.۸ %. However, the presence of Pb metal in the perovskite crystalline limits the progressof this new generation of solar cells from environmental aspects۱, ۲. Here, we have systematicallyinvestigated the impact of the decomposition of perovskite material on the plant. We found thatthe influence of the decomposition of a perovskite solar cell has lower destruction than commercialPbI۲. In particular, influenced the roots and leaves to be slower and smoother. Remarkably, theamount of water absorption with the plant's root is lower than, indicating that dramatically wastedwater from roots shows the most harm. In the following, the atomic absorption spectroscopymeasured the lead concentration of the plants ashe which conclude that the plant absorbed morePb metal from commercial PbI۲ than perovskite, This paper opens new avenues and challengesabout the actual scenario on the impact of perovskite materials in PSCs on the plant and livemetabolisms. Therefore, we conclude that the plant absorbedmore Pb metal from commercial PbI۲ than perovskite of a PSC,which is in contrast with recent report in NatureCommunications paper۳. This paper opens new avenues andchallenges about the actual scenario on the impact of perovskitematerials in PSCs on the plant and live metabolisms.
