Tiny Sunflowers That Bend Toward Light and Harvest Solar Energy Created by U.S. Scientists

Scientists in the U.S. have created an artificial sunflower less than 0.04 inches wide that can bend towards a light source and harvest solar energy.

The flowers, dubbed SunBOTs, were found to be about 400 percent more efficient than comparable devices that are stationary, making them a promising technology for solar power—potentially even as a power source for solar-based spaceships.

The team, led by researchers from the University of California, Los Angeles, were looking to improve the efficiency of solar cells by emulating a feature of nature—phototropism. This is where a plant orientates itself to face the sun, optimizing the amount of energy it can get. In a study published in Nature Nanotechnology, the team said achieving tropistic behavior in a synthetic material has been a “daunting challenge.”
