Substantial boosts to the efficiencies of solar panels can be achieved by utilizing micro-machined, nearly flat, Fresnel lenses, according to new research from Tianjin University in China.The improvements are the result of a new technology that allows for the crafting of an array of microscopic cones on the Fresnel lens — these cones, used instead of concentric ridges, allow for a more precise control of the depth to which the light is focused by the lens.
