Title (EN) METHOD FOR ACTIVATION OF CDTE LAYER OF CDTE THIN-FILM SOLAR CELLS WITH CALCIUM HYPOCHLORITE
(FR) PROCÉDÉ D'ACTIVATION D'UNE COUCHE DE TELLURURE DE CADMIUM (CDTE) DE CELLULES SOLAIRES CDTE EN COUCHES MINCES AVEC DE L'HYPOCHLORITE DE CALCIUM
Abstract:
(EN) A method for activating the CdTe laye r(4) of semi-finished thin-film CdTe solar cell is described, in which the CdCl 2 used in prior art is at least partially replaced by a less hazardous, cheaper and easy to handle substance, wherein the overall method of producing a CdTe thin-film solar cell is maintained. This is achieved by applying calcium hypochlorite onto the CdTe layer (4) and the subsequent heat treatment of the semi-finished thin-film CdTe solar cells.
(FR) L'invention concerne un procédé d'activation de la couche de CdTe (4) d'une cellule solaire CdTe en couches minces semi-finie, selon lequel le CdCl2 utilisé dans l'état de la technique est au moins partiellement remplacé par une substance moins dangereuse, moins coûteuse et facile à manipuler, le procédé global de production d'une cellule solaire CdTe en couches minces étant conservé. Ceci est obtenu par l'application d'hypochlorite de calcium sur la couche de CdTe (4) et le traitement thermique ultérieur des cellules solaires CdTe en couches minces semi-finies.
