Inspired by art, lightweight solar cells track the sun

Solar cells capture up to 40 percent more energy when they can track the sun across the sky, but conventional, motorized trackers are too heavy and bulky for pitched rooftops and vehicle surfaces. Now, by borrowing from kirigami, the ancient Japanese art of paper cutting, researchers have developed solar cells that can have it both ways.
