    Abstract: Methods of manufacturing photovoltaic modules are provided. One method includes providing a substrate and depositing a lower electrode above the substrate. The method also includes depositing a lower stack of microcrystalline silicon layers above the lower electrode, depositing an upper stack of amorphous silicon layers above the lower stack of microcrystalline silicon layers, and depositing an upper electrode above the upper stack of amorphous silicon layers. At least one of the lower stack and the upper stack includes an N-I-P stack of silicon layers having an n-doped silicon layer, an intrinsic silicon layer, and a p-doped silicon layer. The intrinsic silicon layer has an energy band gap that is reduced by depositing the intrinsic silicon layer at a temperature of at least 250 degrees Celsius.
