Abstract The development of molecule-based selective contacts has boosted the power conversion efficiencies of inverted perovskite solar cells. However, these molecular films, often assembled as monolayer or multiple layers on the substrate, are prone to molecular desorption and structural deformation, limiting the long-term stability of devices.

Abstract Metal halide perovskite solar cells combine high power density with low-cost manufacturing, but durability under repeated extreme temperature cycling remains insufficiently understood. We investigate thermal fatigue under cycling between −80 °C and +80 °C as an accelerated stress protocol. Mismatched thermal expansion between the perovskite absorber and glass substrate induces biaxial tensile strain, leading to degradation at the substrate–perovskite interface and within grain boundaries.
