An electric energy generating module is shaped to take on a desired two dimensional profile to match a non-flat surface or architectural element such as corrugated roofing. The module includes an electric energy generating film sealed between a top layer of encapsulant material and a bottom layer of encapsulant material. The type and quantity of the encapsulant materials are such that the shape of the encapsulant materials can be altered when a high temperature and/or pressure is applied to the module, but where the encapsulant materials provide a rigid structure around the electric energy generating film under ordinary (i.e., naturally occurring) temperature and pressure conditions. The module can therefore be shaped by applying a suitable pressure and/or a high temperature but, once placed under ordinary temperature and pressure conditions, the module has a rigid structure.
