Imagine solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon. Researchers at MIT have now demonstrated just such a technology: the thinnest, lightest solar cells ever produced.
Though it may take years to develop into a commercial product, the laboratory proof-of-concept shows a new approach to making solar cells that could help power the next generation of portable electronic devices.Image credit: Joel Jean and Anna Osherov
