摘　　要：A series of organic photovoltaic （PV） cells in which the electron acceptor and donor are gadolinium （dibenzoylmethanato）3（bathophenanthroline） and N,N′-diphenyl-N,N′bis（3-methylphenyl）-1,1′-diphenyl-4,4′-diamine , respectively, were fabricated. Although TPD acts as an active layer in the bilayered cells, insertion of a Gd-complex film between TPD and the alloy cathode is necessary for efficient carrier photogeneration. Open-circuit voltage of 3.2 V is obtained due to efficient exciton dissociation near the interface between （Gd（DBM）3bath） and TPD. By incorporating an ultrathin mixed layer of Gd-complex and TPD, external quantum efficiency is improved significantly.It was found that photovoltaic performance of the devices has a common origin, exciplex formation, which results in broadband emission during both photoluminescent and the electroluminescent processes.A series of organic photovoltaic (PV) cells in which the electron acceptor and donor are gadolinium (dibenzoylmethanato)_3(bathophenanthroline) and N,N′-diphenyl-N,N′bis(3-methylphenyl)-1,1′-diphenyl-4,4′-diamine , respectively, were fabricated.
