Light- and Elevated-temperature testing appears to be critical to the durability of metal-halide perovskite modules. In this work we describe our progress towards understanding the relationship between light- and elevated-temperature testing and outdoor degradation of perovskite PV modules. This is achieved by testing modules indoors under 1-sun of light and different temperature conditions and fielding modules outdoor in Golden, Colorado. We also demonstrate how packaging design can impact perovskite module durability where vacuum laminated modules with a polymer encapsulant are significantly more durable than modules without a polymer encapsulant in outdoor testing.
