Abstract
An absorber layer of a photovoltaic device may be formed on an aluminum or metallized polymer foil substrate. A nascent absorber layer containing one or more elements of group IB and one or more elements of group IIIA is formed on the substrate. The nascent absorber layer and/or substrate is then rapidly heated from an ambient temperature to an average plateau temperature range of between about 200° C. and about 600° C. and maintained in the average plateau temperature range 1 to 30 minutes after which the temperature is reduced.
