1-micrometer-thin flexible solar cells can wrap around a pencil

Rooftop panels are perhaps the most common use for solar cells. But what if they could be used to power smaller things, like wearables? That's exactly what scientists from South Korea are pursuing. They designed super thin, flexible solar cells that can wrap around a pencil, and could potentially be used in items like smart glasses or fitness trackers.
