Fusion-formable sodium-containing aluminosilicate and boroaluminosilicate glasses are described. The glasses are particularly useful for controlled release of sodium—useful in semiconductor applications, such as thin film photovoltaics where the sodium required to optimize cell efficiency is to be derived from the substrate glass.
