Solar power plants can efficiently absorb the perovskite lead in solar cells

Hybrid halide perovskite can preparation efficient solar cells, solar power network in China, at the same time has good performance, low cost, the characteristics of huge commercial value, therefore has attracted much attention. Solar photovoltaic (pv) survey and in addition, although there are calculations show that solar power grid, 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, solar power network, it is not clear. The researchers point out, in front of the large-scale deployment of the material, deal with different components of the environmental impact of perovskite more systematic investigation. Chest back two splicing helmholtz Berlin material and energy center scientists Antonio & middot; , white and his colleagues, mint, pepper, and cabbage plant cultivation in laboratory in lead-based perovskite contaminated soils, and to measure their ability to absorb lead. In other to carry out a series of experiments, the team found that if the change will lead in the battery tin, solar photovoltaic power generation system eventually plant intake of tin maximum tolerance under the United Nations food and agriculture organization (fao). Results found that polycrystalline silicon reduction furnace images the bioavailability of lead in perovskite was 10 times higher than the other lead pollution sources in the lead. Chest back two splicing think at present, the study of the theory of the perovskite solar cells has yet to be strengthened. Now, the use of perovskite type organic metal halide semiconductor as a material suction light of solar cells, solar panels, solar photovoltaic (pv) survey and be regarded as the third generation solar cells ( First generation refers to monocrystalline silicon and polycrystalline silicon solar cells, and the second generation mainly including amorphous silicon thin-film batteries and polycrystalline silicon thin-film batteries) , the difference between the wafer and chip is also called the new concept of solar cells. Plants can efficiently absorb the perovskite lead in solar cells, but in front of the mass use of the material should be more system survey its environmental impact journal of science and technology Beijing January 22 (Reuters) - Reporter Zhang Mengran) According to the natural & middot; 21 communications magazine published a report in environmental studies, solar panels, and, according to a study by German scientists the difference between the wafer and chip compared with the soil lead pollution caused by human activity, hot domestic software from perovskite lead into the part of the solar cell efficiency is 10 times of the former in plant.
