Cylindrical Fresnel lens: An innovative path toward a tracking-less concentrating photovoltaics system

We here invent an implicitly new optical device - cylindrical Fresnel lenses historically used in the decades-old lighthouse concentrator to find application in the field of concentrator photovoltaic, with numerous demonstrations of exotic features in optics. The precious attribute of such a solar c...
