However solar panels are not emitting toxins into the atmosphere as they re generating electricity.
Non toxic solar panels.
Additionally to produce solar panels manufacturers need to handle toxic chemicals.
With recycling expensive.
Their work was published online june 11 in chemistry of materials.
A team of engineers at washington university in st.
In contrast perovskite compounds readily dissolve in water.
Silicon solar panels can contain trace amounts of lead in the glass that encases the cells active components but it is insoluble.
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.
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.
