摘要：A method of processing a plurality of photovoltaic materials in a batch processincludes providing at least one transparent substrate having an overlying first electrode

layer and an overlying copper species based absorber precursor layer within an internalregion of a furnace. The overlying copper species based absorber precursor layer has anexposed face. The method further includes disposing at least one soda lime glasscomprising a soda lime glass face within the internal region of the furnace such that thesoda lime glass face is adjacent by a spacing to the exposed face of the at least onetransparent substrate. Furthermore, the method includes subjecting the at least onetransparent substrate and the one soda lime glass to thermal energy to transfer one ormore sodium bearing species from the soda lime glass face across the spacing into thecopper species based absorber precursor layer via the exposed face.
