Analysis of Anomalous Discharging Processes in Pentacene/C60 Double-Layer Organic Solar Cell

Optical electric-field-induced second-harmonic generation (EFISHG) measurement was employed for studying interfacial processes in pentacene/C60 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.
