Stacks of teeny lenses that look like inverted pyramids could juice up solar panels, helping them capture more light from any angle on both sunny and overcast days. Solar panels perform best in direct sunlight, which is why some solar systems track the big fireball across the sky, turning to face it for maximum light. […]
Nina Vaidya of Stanford University has designed a sophisticated device that can harvest and concentrate light efficiently, no matter what the angle and frequency of the light.
A device that can capture 90% of the light that falls on it, regardless of its angle or frequency, and concentrate it to be 3x brighter onto a solar cell.
