Abstract:
1. A method for processing a thin film photovoltaic module, the method comprising: subjecting a plurality of substrates to a desiccated environment having a relative humidity of less than about 10%, wherein each substrate of the plurality of substrates includes an absorber layer overlying a first electrode, and wherein the absorber comprises a plurality of sodium bearing species having a sodium concentration of at least about 5×10 subjecting the plurality of substrates to a liquid comprising water at a temperature from about 10 degrees Celsius to about 80 degrees Celsius to process the plurality of substrates; subjecting the plurality of substrates to an environment having a relative humidity of greater than about 10% to a time period of less than four hours; and after the step of subjecting the plurality of substrates to a liquid, forming a window layer over the absorber layer.
