| Abstract(in English) | By using electric-field-induced optical second-harmonic generation (EFISHG) measurement, we probed the internal electric field formed in double-layer organic solar cells (OSCs) with and without bathocuproine (BCP) interface layer (IZO/pentacene/C_<60>/Al and IZO/pentacene/C_<60>/BCP/Al). Results showed that, in OSCs without BCP layer, the internal field (|E_0|=1.6×10^4 V/cm) is pointing in the direction from the IZO to the Al electrode in OSCs without BCP layer, whereas the internal field (|E_0|=6.7×10^4 V/cm) is pointing from the Al electrode to the IZO electrode in OSCs with BCP layer. In the OSCs with BCP layer, the internal field conveys holes (electrons) to the IZO (Al) electrode. As the result, short-circuit current under illumination is enhanced in the OSCs with the BCP layer. |
