This disclosure provides photovoltaic modules and methods of making the same. In one implementation, a photovoltaic module includes a plurality of photovoltaic devices configured to absorb light and generate electrical power and a plurality of conductors disposed over the photovoltaic devices. The photovoltaic module further includes a glass layer disposed over the photovoltaic devices, and the glass layer includes a textured surface opposite the plurality of photovoltaic devices. The textured surface includes features configured to diffract light incident the photovoltaic module. The photovoltaic module further includes a diffusive layer disposed over at least a portion of the plurality of conductors.
