A photovoltaic device and method of manufacture provides a P-N junction formed between doped semiconductor materials and adapted to produce photovoltaic current in response to radiant energy reaching the P-N junction, and a silicon dioxide protective window layer located in proximity to doped semiconductor material and adapted to allow radiant energy to pass there through en route to the P-N junction, the protective layer including a high optical transparency layer of amorphous silica, having a silicon dioxide chemistry greater than 75 molar percent (75 mol %). A photovoltaic window provides a planar photovoltaic device being at least semi-transparent; and a pair of protective window layers sandwiched around the planar photovoltaic device and adapted to allow radiant energy to reach the photovoltaic device through both protective window layers, wherein at least one protective window layer is a high optical transparency layer of amorphous silica, having a silicon dioxide chemistry greater than 75 molar percent (75 mol %)
