CsPbI3 perovskite solar cells have attracted intense research interest since the inorganic absorber layer has better thermal stability compared with organic-inorganic hybrid perovskites. However, CsPbI3 suffers from structural instability due to an easily induced phase transition from the photoactive to the photoinactive structure. Here, we …
We investigated potentially hazardous chemicals from Pb-based perovskite solar cells on two crop plants (mungbean and sorghum). The direct exposure of a single chemical (PbI 2) on the soil environment was simulated, plant soil was assayed, and its phytotoxicity was subsequently evaluated. After 21 days of exposure, we observed …
Currently, the photovoltaic performance of perovskite solar cells (PSCs) is closely linked to undermined defects in the perovskite, and the correct approach to ensure stability under practical conditions is still in dispute. Therefore, natural, healthy, and low‐cost additives are expected to not only reduce the trap sites but also drastically improve …

You don't have to venture far to obtain High-Purity Ore Ore: the area just past the Mouth has 7 nodes where you can obtain this Ore. After looting the ore, you can return to the Mouth to refresh the nodes. Otherwise, keep going east, along the lower path, towards the next signpost for 6 more nodes. Tip

In this work, we find that the iodide in MAPbI 3 causes greater harm to plants than the lead. Model species Arabidopsis thaliana was used to study the effect of MAPbI 3 and different perovskite precursors on the growth and development of plants. Unlike previous work on perovskite toxicity (Babayigit et al., 2016a; Li et al., 2020), we …

Perovskites are generally assumed to be toxic because of the lead (Pb), but experimental evidence to support this prediction is scarce. We tested the toxicity of the perovskite MAPbI3 (MA = CH3NH3) and several precursors in Arabidopsis thaliana plants. Both MAPbI3 and the precursor MAI hamper plant growth at concentrations above 5 μM.
