Louis has found what they believe is a more stable less toxic semiconductor for solar applications using a novel double perovskite oxide discovered through data analytics and quantum mechanical calculations.
Non toxic solar panels.
Environmental scientists and solar industry leaders are raising the red flag about used solar panels which contain toxic heavy metals and are considered hazardous waste.
However solar panels are not emitting toxins into the atmosphere as they re generating electricity.
In collaboration with colleagues at mit the national renewable energy laboratory and colorado school of mines in the us the cambridge researchers have shown that bismuth which sits next to lead in the periodic table could be a non toxic alternative to lead for use in next generation solar cells.
Silicon solar panels can contain trace amounts of lead in the glass that encases the cells active components but it is insoluble.

In contrast perovskite compounds readily dissolve in water.
Whether the lead contained within perovskite solar cells represents a tangible risk to humans animals and the environment is being debated however some scientists are now searching for non toxic.
Additionally to produce solar panels manufacturers need to handle toxic chemicals.
