N2 - In this essay, the authors use two properly encapsulated high‐efficiency
mesoscopic perovskite solar cells (PSCs), which use a state‐of‐the‐art
perovskite composition (HC(NH2)2PbI3)0.85(CH3NH3PbBr3)0.15 with excess PbI2
as the active layer, to demonstrate the potential effect of dynamical
electroluminescence responses on the analysis and interpretation of PSCs
electrical characteristic. The essay does not aim to determine how to
overcome this issue, nor to investigate its physical/chemical origin,
although tentative propositions are made; but rather, to warn
researchers in the field about the interpretation and reporting the
results obtained from luminescence imaging measurements and the effect
of image collection timing on the results. This is a critical message
since the authors predict that luminescence imaging techniques will soon
become one of the key tools for PSCs characterization, both for
long‐term stability assessment and fabrication process optimization.
