Lack of proven stability has become a major obstacle on the path of metal halide perovskite solar cells (PSCs), in particular methylammonium lead triiodide (MAPbI 3 ), towards commercial viability. This correlates with the intrinsic affinity of MAPbI 3 towards moisture and ambient air in particular, leading to its degradation in ambient conditions. We performed extensive stability tests to prove the durability of hole‐conductor‐free PSCs based on a triple‐layer architecture employing carbon as a back contact, including outdoor tests in the hot desert climate and indoor long‐term light soaking as well as heat exposure during 3 months at 80–85 °C. These results show no evidence for device degradation under the test conditions, confirming that the triple‐layer device architecture provides a promising path towards realizing efficient and stable perovskite photovoltaics.
