Abstract
We demonstrate organic photovoltaic cells composed of multi charge-separation (MCS) interfaces in the active layer for the improvement of power conversion efficiency (ηp). The MCS interfaces are composed of pentacene/C60 and Zn-phthalocyanine (ZnPc)/C60 by inserting thin layer of ZnPc at the CS interface between pentacene/C 60. We obtain enhanced ηp and Voc in accordance with the increased energy difference between the lowest unoccupied molecular orbital (LUMO) level of the n-type material (C60) and the HOMO level of the p-type material (ZnPc). By inserting 2nm ZnPc at the interface, both open-circuit voltage (Voc) and short-circuit current density (Jsc) have been improved simultaneously and the resulting ηp reaches 2.07%.
