A Dab of Sunscreen Key To Solar Windows That Last Decades

A new approach by the University of Michigan in Ann Arbor might dramatically extend the working life of solar windows. In a new study, researchers said their solar cell design can operate at high efficiencies for up to 30 years—roughly on par with the expected lifetime of conventional silicon solar panels. Now, the team is working to scale their speck-sized device to match the dimensions of a small window.
