- Abstract
- In this review, recent researches on ion transport phenomena in organic metal halide perovskite materials, which have been popular all over the world, are summarized. Although different results have been reported depending on the perovskite material composition and applied voltage, iodide seems to migrate under actual solar cell operating conditions, and occasionally methylammonium migration is observed. Perovskite is a so-called mixed conductor in which electrons and ions move simultaneously at room temperature, which greatly influences the hysteresis of the perovskite solar cell current-voltage curve and the performance degradation due to long-term operation.
