Optical electric-field-induced second-harmonic generation (EFISHG) measurement was employed for studying interfacial processes in pentacene/C-60 double-layer organic solar cells (OSCs). Results showed that charging and discharging on the double-layer interface by photoillumination were nonreversible, and a recharging process continued after the illumination stopped. The Maxwell-Wagner model analysis revealed that the photoconductance change is responsible for this anomalous interfacial recharging. The results of impedance spectroscopy (IS) analysis supported this conclusion.
