The present situation with respect to current–voltage measurement standards for metastable photovoltaics, including perovskites, is discussed. New draft updates to the IEC 60904-1 standard do not fully capture the needs of metastable devices. A new document within the 60904 series capturing the academically favoured SPO and MPPT methods would go a long way toward solving the present ambiguity, however the lack of an effective stabilisation procedure remains the greatest hurdle for perovskite PV.
