CAPSUN Technologies and GHENOVA Ingeniería have jointly developed the SPIRE and BLUESOLAR project, a disruptive technology that integrates the best characteristics of Photovoltaic (PV) and Concentration Solar Plants (CSP).
The concept is simple: by means of a selective optical filter, the light spectrum is divided. The filter allows the efficient passage of the radiation used by the photovoltaic panel (mainly visible light) while reflecting 40% of the energy (mainly blue and infrared light). This technology does not lose in comparison with a 1 axis photovoltaic plant. SOLAR BLUE converts the heat that currently overheats the photovoltaic cells into thermal energy (using a Tower-CSP-TES system).
