Metal-Halide Perovskite (MHP) photovoltaic (PV) modules are at the cusp of commercialization. One of the major hurdles that remains is establishing confidence in long-term durability. This work proposes an initial accelerated stress testing protocol that can be used as the foundation for the development of a standardized test procedure for qualification of commercial MHP modules. We apply the protocol to three different MHP module architectures to identify the critical degradation pathways that will inform future testing development. In addition, the modules are exposed to outdoor environments such that a cross-examination with indoor results can be used to verify the relevance of the indoor stress conditions.
