ANNEALING MATERIALS AND METHODS FOR ANNEALING PHOTOVOLTAIC DEVICES WITH ANNEALING MATERIALS

Abstract:

A method for annealing an absorber layer is disclosed, the method including contacting a surface of the absorber layer with an annealing material provided as a gel. The annealing material comprises cadmium chloride and a thickening agent. A viscosity of the gel of the annealing material is greater than or equal to 5 millipascal seconds.
