TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The phosphorescent particle is sulfides or selenide or phosphoric oxides. Phosphorescent particles are zinc sulfides or alkaline-ferrous aluminate doped with rare earth particles. The fluid coolant is water, or water added with antifreeze e.g. ethylene glycol or propylene glycol. The mass concentration of photoluminescent particles in coolant is 0.1-30%. The coolant comprising nano-particles allowing the appearance of the phenomenon of division of quantum and/or allowing the conversion wavelength of the photons re-emitted in the ultraviolet spectrum towards that of the visible one.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The zone of culture includes a closed photo-bioreactor. The zone of culture is zone with open sky, i.e. with the ambient air. The heat exchanger is integrated in the circuit of fluid of coolant containing the phosphorescent particles of luminophores in suspension. The heat exchanger is integrated within the solar panel. The heat exchanger is integrated within the zone of culture. The enclosure of the solar panel is glass or transparent polymer with the solar radiation. The chamber of the solar panel comprises a wall forming a bottom, opposed to a wall transparent to the solar radiation, the bottom being black color. The chamber of photo-bioreactor is made of transparent material plates with the visible radiation, e.g. PVC or polycarbonate. The enclosure of photo-bioreactor consist of tubular exchanger with channels of circulation of the fluid charged in phosphorescent particles, right form lengthened according to the axis of the tube of the enclosure. The enclosure of photo-bioreactor consists of a plate heat exchanger superimposed, with channels of circulation of the fluid charged in phosphorescent particles through the plates which just like extend according to their length from the plates of channels from circulation from the culture medium. The solar panel comprises a solar concentration device.
