Embodiments of the present disclosure generally relate to flexible photovoltaic modules that include a multi-layered substrate. In some embodiments, the multi-layered substrate includes one or more layers that are configured to improve the elastic modulus, rigidity, or stiffness of a flexible substrate of a flexible photovoltaic module during a deposition process step at an elevated temperature that is used to form the flexible photovoltaic module. The one or more layers of the multi-layered substrate may also provide improved barrier properties that prevent environmental contaminants from affecting the performance of a formed photovoltaic module, which includes the multi-layered substrate, during normal operation.
