A full overview of international standards assessing the long-term stability of perovskite solar cells

Perovskite solar cells have emerged as promising candidates for photovoltaics. Passing existing standards is a necessary minimum requirement for a possible commercialisation. Here, we analyse the most current international stability standards and to which degree perovskites have passed them. We then elaborate on the most pertinent challenges for the long-term stability of perovskites in the coming years.
