Abstract

Although the record efficiencies of perovskite hybrid solar cells are gradually reaching the efficiency of crystalline Si solar cells, perovskite hybrid solar cells often exhibit significant current density-voltage (J-V) hysteresis with respect to the forward and reverse scan direction and scan rate. The origin of the J-V hysteresis of perovskite hybrid solar cells has not, to date, been clearly elucidated. Dielectric polarization by the ferroelectric properties of perovskite (i), the ionic motion/migration of perovskite materials (ii), and charge trapping and detrapping at trap sites by the unbalanced electron and hole flux (III) are considered the possible origins of J-V hysteresis. Here, we reviewed the origin of the J-V hysteresis of perovskite solar cells from the above three points of view and we then suggest how one may reduce the J-V hysteresis with respect to the scan direction and scan rate.
