Perovskite solar cells have demonstrated the efficiencies needed for technoeconomic competitiveness. With respect to the demanding stability requirements of photovoltaics, many techniques have been used to increase the stability of perovskite solar cells, and tremendous improvements have been made over the course of a decade of research. Nevertheless, the still-limited stability of perovskite solar cells remains to be fully understood and addressed. In this Review, we summarize progress in single-junction, lead-based perovskite photovoltaic stability and discuss the origins of chemical lability and how this affects stability under a range of relevant stressors. We highlight categories of prominent stability-enhancing strategies, including compositional tuning, barrier layers and the fabrication of stable transport layers. In the conclusion of this Review, we discuss the challenges that remain, and we offer a perspective on how the field can continue to advance to 25-year and 30-year stable perovskite solar modules.
