Title (EN) ANNEALING PROCESSES FOR PHOTOVOLTAICS
(FR) PROCESSUS DE RECUIT POUR ÉLÉMENTS PHOTOVOLTAÏQUES
Abstract:
(EN) Processes for making a solar cell by depositing various layers of components on a substrate and converting the components into a thin film photovoltaic absorber material. Processes of this disclosure can be used to control the stoichiometry of metal atoms in making a solar cell for targeting a particular concentration and providing a gradient of metal atom concentration. A selenium layer can be used in annealing a thin film photovoltaic absorber material.
(FR) La présente invention concerne des processus de fabrication d'une photopile par dépôt de diverses couches de composants sur un substrat et conversion des composants en un matériau absorbant photovoltaïque à couche mince. Ces processus peuvent être utilisés pour commander la stœchiométrie d'atomes métalliques lors de la fabrication d'une photopile pour cibler une concentration particulière et fournir un gradient de concentration d'atome métallique. Une couche de sélénium peut être utilisée lors du recuit d'un matériau absorbant photovoltaïque à couche mince.
