| Abstract: | We demonstrate organic photovoltaic cells composed of multi charge-separation (MCS) interfaces in the active layer for the improvement of power conversion efficiency (η_P). The MCS interfaces are composed of pentacene/C_<60> and Zn-phthalocyanine (ZnPc)/C_<60> by inserting thin layer of ZnPc at the CS interface between pentacene/C_<60>. We obtain enhanced η_P and V_<oc> in accordance with the increased energy difference between the lowest unoccupied molecular orbital (LUMO) level of the n-type material (C_<60>) and the HOMO level of the p-type material (ZnPc). By inserting 2 nm ZnPc at the interface, both open-circuit voltage (V_<oc>) and short-circuit current density (J_<sc>) have been improved simultaneously and the resulting η_P reaches 2.07%. |
