Moth’s eye and lotus leaf inspire more efficient, easier to maintain solar panels

Just as the cost of solar energy has been dropping precipitously, innovations sprout to accelerate the trend while improving the technology. In a recent example of biomimicry applied to solar, Oak Ridge National Lab was inspired by the moth’s eye to create an antireflective coating that increases solar conversion efficiency up to 6 percent, and by the lotus leaf to make that coating highly water repellent—essentially self-cleaning since bouncing rain drops collect dust and particles.
