In other to carry out a series of experiments, the researchers found that if the change will lead in the battery tin, solar portal, photovoltaic (pv) grid, eventually tin intake is below the United Nations food and agriculture organization (fao) to set up the biggest tolerance. Cool storage heat storage technology construction project management software despite calculations show that the weight of the perovskite membrane lead in is less than 0. 1% - — Below the safety limits set by the many countries, but these lead environmental impact is unclear. EVA back recently, according to a study that compared with the soil lead pollution caused by human activity, from perovskite lead into the part of the solar cell efficiency is 10 times of the former in plant. Relevant papers recently published in nature & ndash; Communication '. Helmholtz Berlin material and energy center of Antonio Abate and colleagues, solar panels, in the laboratory using lead-based perovskite contaminated soil culture of mint, pepper, and cabbage plants, solar energy, solar photovoltaic power generation project and to measure their ability to absorb lead. Photovoltaic engineering Abate, points out that solar portal, chest back how fixed according to the study, in front of the large-scale deployment of the material, deal with different environmental impact more system composed of perovskite screening. Hybrid halide perovskite can be prepared and efficient solar cells. The researchers found that the bioavailability of lead in perovskite was 10 times higher than the other lead pollution sources.
