NOVELTY - The low alkali and/or low sodium photovoltaic glass laminated and layered article (100) comprises a transparent glass layer (12) having a strain point of greater than or equal to 500 degrees C, a photovoltaic functional material (10) disposed on the glass layer, a substrate (16) comprising a glass and/or a polymer and having a thickness greater than that of the glass layer, a laminate layer (14) disposed between the substrate and either the glass layer or the photovoltaic functional material, and a protective layer disposed on a surface of the photovoltaic functional material not in contact with the glass layer.    USE - The article is useful for photovoltaic devices for roof top applications on buildings (commercial and residential) and on-off grid.    ADVANTAGE - The article: is capable of minimizing or estimating or controlling alkali diffusion and/or sodium diffusion into the functional material from the glass, and reducing defects in the glass; and has increased clarity and minimized weight.    DETAILED DESCRIPTION - The low alkali and/or low sodium photovoltaic glass laminated and layered article (100) comprises a transparent glass layer (12) having a strain point of greater than or equal to 500 degrees C, a photovoltaic functional material (10) disposed on the glass layer, a substrate (16) comprising a glass and/or a polymer and having a thickness greater than that of the glass layer, a laminate layer (14) disposed between the substrate and either the glass layer or the photovoltaic functional material, and a protective layer disposed on a surface of the photovoltaic functional material not in contact with the glass layer. The glass layer has a thickness of less than or equal to 2 mm. The glass layer has a strain point of greater than or equal to 540 degrees C. The coefficient of thermal expansion of the glass layer is 30x 10-7/ degrees C to 60x 10-7/ degrees C. The glass layer is fusion formable.
