Abstract: A device for transformation of concentrated solar energy including a photovoltaic cell and laser device, which includes a first reflecting mirror adapted for entry of a beam of solar rays and a second reflecting mirror adapted for an outlet of a laser beam, with the first reflecting mirror reflective on an outlet wavelength of the laser beam and transparent to a totality of a solar spectrum and the second reflecting mirror partially reflective on the wavelength of the laser beam, reflective in an interval of the solar spectrum which is absorbed and transparent in other wavelengths different to these, and at the outlet of the laser beam. The device includes a nucleus doped with substances for total or partial absorption of the solar spectrum and coatings.

Abstract: A solar receiver having a higher yield than a central tower receiver. The receiver comprises a plurality of absorbent tubes for absorbing incident energy from light guides suitable for capturing solar radiation in solar collector concentration focal points, the absorbent tubes being arranged consecutively and in parallel, adjacently in relation to a direction transverse to the longitudinal axis of the absorbent tubes. The tubes contain a circulating heat-transfer fluid. The longitudinal axes are contained in at least two planes, defining at least two lines of absorbent tubes arranged in an alternating manner, and partially superimposed. The receiver also comprises containers subjected to a vacuum in order to enclose the absorbent tubes and reduce losses by convection.

Abstract: A solar plant enabling transformation of solar energy exploiting most of the solar spectrum with very efficient yields, including: at least one solar collector including a concentrator, configured to collect and concentrate solar radiation in the concentrator; a solar laser device to transform radiation received from the concentrators into laser radiation; a receiver and/or a solar reactor configured to receive radiation from the laser device and transform it into another form of energy; and can include flexible lightguides or plane mirrors to transport the radiation received from the laser device to the solar reactor and/or receiver, and photovoltaic cells interspersed among the collectors and laser devices to transform the concentrated radiation into electricity and allow radiation not transformed to pass to the laser devices.
