What is Parameters Affecting I – V Hysteresis of CH~3~NH~3~PbI~3~ Perovskite Solar Cells: Effects of Perovskite Crystal Size and Mesoporous TiO~2~ Layer about?
Current-voltage (I-V) characteristics of CH 3 NH 3 PbI 3 perovskite solar cells are studied using a time-dependent current response with stepwise sweeping of the bias voltage. Compared to the crystalline Si solar cell showing time-independent current at a given bias voltage, the perovskite solar cells exhibit time-dependent current response. The current increases with time and becomes steady at forward scan (FS) from short-circuit to open-circuit, whereas it is decayed and saturated with time at reverse scan (RS) from open-circuit to short-circuit. Timedependent current response eventually leads to I-V hysteresis depending on the scan direction and the scan rate. Crystal size of CH 3 NH 3 PbI 3 and the mesoporous TiO 2 (mp-TiO 2 ) film are found to influence I-V hysteresis, where the I-V hysteresis is alleviated as crystal size increases and in the presence of mp-TiO 2 . The capacitance observed at low frequency (0.1-1 Hz), associated with dipole polarization, tends to diminish as size of perovskite and mp-TiO 2 layer thickness increase, which suggests that the origin of hysteresis correlates to the capacitive characteristic of CH 3 NH 3 PbI 3 and the degree of hysteresis depends s
