Abstract

Un module de conversion d'énergie photo-thermique (100) comporte des première et seconde parois (102, 104) qui s'étendent dans différents plans parallèles, plusieurs parois de séparation (106-I) qui entrent en contact avec les première et seconde parois (102, 104) et s'étendent perpendiculairement aux première et seconde parois (102, 104), une chambre interne (110) définie par la première paroi (102), la seconde paroi (104) et les première et seconde parois de séparation des multiples parois de séparation (106-1), et un mélange particulaire (211) distribué autour de la chambre interne (110), le mélange particulaire (211) comportant un composant organique (212) et un composant inorganique (214). Le composant organique (212) est configuré pour absorber une première quantité de lumière proche infrarouge, NIR, (424) présentant une longueur d'onde supérieure à 700 nm et pour générer une première quantité de chaleur, le composant inorganique (214) est configuré pour absorber une seconde quantité du NIR (424) présentant une longueur d'onde supérieure à 700 nm et pour générer une seconde quantité de chaleur, et les première et seconde parois comportant une matrice polymère (210) qui est configurée pour permettre le passage de la lumière visible (422), la lumière visible (422) présentant une longueur d'onde comprise entre 400 et 700 nm.
