technique in mixed conductor investigations24,27,28. When the current was switched on from 0 to 20 pA, the measured resistance immediately reached an initial value and then gradually increased to a stable value (Figure 2b). The ionic migration and accumulation are the rate-determining processes...
to impact upon the photovoltaic performance of these materials. Methylammonium lead iodide perovskite (MAPI) and Formamidinium lead iodide (FAPI) photovoltaic cells, being the most familiar archetypal HOIPs, are comparatively inexpensive and also easy to assemble11. Recently, MAPI solar cell has gaine...
