The photovoltaic properties of hybrid organic–inorganic perovskites are sensitive to the local microstructure, but difficult to quantify at the nanoscale. Leblebici et al. use conductive atomic force microscopy to map the local short-circuit current and open-circuit voltage, finding heterogeneity within individual grains.
