A system or device for concentrating the light radiation of the type to be used for converting the solar radiation into electric current and/or thermal energy is disclosed. The device mainly having a primary optics apt to be exposed to the solar radiation and to allow the passage thereof therethrough, the primary optics being positioned on a hollow spacer member, which is perfectly aligned and at the same time locked, by means of a joint member.

Assembly for converting solar radiation into electric and/or thermal energy

Disclosed is an optical system for concentrating effective light the wavelength whereof is comprised between two limit values (&#x3bb;, &#x3bb;), comprising: an aspheric lens adapted for receiving and refracting the sunlight and provided with a convex lower portion defining a lower face with curved profile consisting of a predetermined number of curvatures with common tangency points in the contact points between two contiguous curvatures and which therefore provides for different focal points, each one corresponding to a wavelength value of effective light, comprised within the range defined by two focal points (f, f) respectively corresponding to said limit values (&#x3bb;, &#x3bb;); an optical manifold with tapered shape, internally hollow and provided with an internal reflecting surface; said manifold extending from a larger base, facing said lower portion of the aspheric lens, to a smaller base and being adapted for receiving the effective light therein, focused by said aspheric lens, and for reflecting the effective light portion that does not directly hit the receiving surface interfaced with the smaller base of said optical manifold; and a photovoltaic cell facing the smaller base of the manifold and provided with a predetermined number of respectively superimposed layers, each layer being intended for absorbing light rays of predetermined wavelengths coming from a corresponding capture area of the aspheric lens and/or from the manifold, so as to have on said photovoltaic cell, a distribution of light energy with a predetermined homogeneity level.
