Many efforts have been made towards improving perovskite (PVK) solar cell stability, but their thermal stability, particularly at 85 °C (IEC 61646 climate chamber tests), remains a challenge. Outdoors, the installed solar cell temperature can reach up to 85 °C, especially in desert regions, providing sufficient motivation to study the effect of temperature stress at or above this temperature (e.g., 100 °C) to confirm the commercial viability of PVK solar cells for industrial companies. In this work, a three‐layer printable HTM‐free CH 3 NH 3 PbI 3 PVK solar cell with a mesoporous carbon back contact and UV‐curable sealant was fabricated and tested for thermal stability over 1500 h at 100 °C. Interestingly, the position of the UV‐curing glue was found to drastically affect the device stability. The side‐sealed cells show high PCE stability and represent a large step toward commercialization of next generation organic–inorganic lead halide PVK solar cells.
