This strategy, outlined in a paper in Nature Electronics, allowed them to fabricate n-type transistors with field-effect mobilities of up to 33 cm 2 V −1 s −1, using formamidinium lead iodide ...

“Lead iodide is a key raw material for organic-inorganic hybrid perovskite solar cells,” so the details of crystal formation are a subject of considerable research interest.

The scientists synthesized formamidinium lead iodide (FAPbI3) into ultrastable, high-quality photovoltaic films for high-efficiency perovskite solar cells.

Once separated, the cleaned lead can then be recycled back to the manufacturers in the form of lead iodide to be used in the creation of more solar cells.

A German research team has developed a new technique to recover and reuse methylammonium lead iodide (MAPbI3) from perovskite solar cells via solvent extraction. Such recycling method can ...

Perovskite solar cells are poised to be the next big photovoltaic technology, after silicon. But they usually don’t last more than a couple of years. They also contain toxic lead, which portends ...
