Optical system provided with aspherical lens for generating electrical energy in a photovoltaic way

摘要: Disclosed is an optical system for concentrating effective light the wavelength whereof comprised between two limit values (λi, λs), comprising: aspheric lens adapted receiving and refracting sunlight provided with a convex lower portion defining face curved profile consisting of predetermined number curvatures common tangency points in contact contiguous which therefore provides different focal points, each one corresponding to value light, within range defined by (fi, fs) respectively said λs); manifold tapered shape, internally hollow internal reflecting surface; extending from larger base, facing lens, smaller base being therein, focused that does not directly hit surface interfaced manifold; photovoltaic cell superimposed layers, layer intended absorbing rays wavelengths coming capture area and/or manifold, so as have on cell, distribution energy homogeneity level.
