One of the cool things about using organic materials for photovoltaic cells is that they can be deposited on plastic, rather than glass, which allows your PV array to bend around curved surfaces. But flexible cells still aren’t the same as skin or fabric: those stretch, too.
In Professor Zhenan Bao’s lab at Stanford, they’re making organic solar cells that are not only flexible but stretchy. One possible application is self-powered “super skin” on artificial limbs.
