Perovskites are used as membrane materials in gas separation. They are being researched for use in solar cells. Perovskites are derived from the mineral perovskite. They have a similar structure, i.e. atoms and molecules are arranged in a similar way. However, they can be made up of different atoms or molecules.<\/p>\n

Because solar cell perovskites are being researched in laboratories (status 2022), consumer do not come into contact with these materials at this time. Before solar cells perovskites are launched on the market, it must be ensured that they will not release toxic substances to humans and the environment. However, the perovskites currently being developed release the toxic heavy metals tin and lead, respectively, when they come into contact with water.<\/p>\n
One possible way to prevent the release of lead and tin from solar cell perovskites would be to safely encapsulate them. This could be done by encasing them in glass. However, there are general safety concerns here, because if the glass is damaged, a release of the heavy metals would again be possible. The problem could be solved if the heavy metals in the solar cell perovskites were replaced by harmless elements or compounds, or if the release of toxic components were impossible.<\/p>\n
From solar cells perovskites containing tin or lead, the heavy metals tin or lead could be dissolved out. Both heavy metals are toxic to humans and environmental organisms and in some cases are also accumulated in plants, animals and fungi. Therefore, a release of the heavy metals must be prevented. However, a hazard currently exists only theoretically, as these solar cells are not sold for installation on rooftops, so they are not on the market (as of 2022).<\/p>\n
If a production or sale of these solar cells containing tin or lead is realized in the future, it must be ensured that no heavy metals are released into the environment or to humans.<\/p>\n

Solar cells perovskites are still research materials in 2022. Studies on the toxicity<\/span> of such materials are useful. There is no danger for private persons at this time, because one cannot buy perovskite solar cells, so one does not come into contact with this material.<\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Perovskites are used as membrane materials in gas separation.
