Title
(EN) CONVERSION OF HEAT ENERGY TO ELECTRICAL ENERGY USING THERMOPHOTOVOLTAIC CELLS
(FR) CONVERSION D'ENERGIE THERMIQUE EN ENERGIE ELECTRIQUE AU MOYEN DE CELLULES THERMOPHOTOVOLTAIQUES
Abstract
(EN)
An apparatus is described for converting heat energy into electrical energy. A heat source (2) produces heat radiation of a broad band spectrum. A rare earth (Ytterbia/Erbia) selective emitter (4) absorbs the heat radiation from the heat source and reradiates narrow band radiation. The narrow band radiation is absorbed by thermophotovoltaic cells (6) that contain multiple quantum well structures and convert the narrow band radiation into electrical energy.
(FR)
L'invention concerne un dispositif servant à convertir de l'énergie thermique en énergie électrique. Une source de chaleur (2) produit un rayonnement thermique possédant un spectre à bande large. Un émetteur sélectif (4) à terres rares (Ytterbium/Erbium) absorbe le rayonnement thermique provenant de la source de chaleur et émet un nouveau rayonnement à bande étroite. Ce rayonnement à bande étroite est absorbé par des cellules thermophotovoltaïques (6) contenant des structures multiples de puits quantiques et convertissant le rayonnement à bande étroite en énergie électrique.
