The present invention relates to a method of fabricating an organic photovoltaic device with improved power conversion efficiency by reducing lateral contribution of series resistance between subcells through active area partitioning by introducing a patterned structure of insulating partitioning walls inside the device. According to the method of the present invention, since the lateral contribution of series resistance between the partitioned subcells is minimized and each subcell works independently, there is no interference phenomenon against the current output of each subcells. As such, the function of a charge extraction layer with high conductivity can be maximized. Thus, the method of the present invention can be effectively used in the fabrication and development of a next-generation large area organic thin layer photovoltaic cell device.

Organic photovoltaic device with improved power conversion efficiency and method of manufacturing same

Organic white-light-emitting blend materials were prepared by light-doping method and electroluminescent devices fabricated using the same, including a transparent substance, translucent electrode, white-light-emitting layer and metal electrode in order, can efficiently control F&#xf6;rster energy transfer in organic light-emitting materials by performing light doping, thus to fabricate a white electroluminescent device using the blend materials which can emit white-light with high efficiency. The white-light-emitting blend materials can be obtained by the light-doping method, in which the energy transfer occurs only between a host which is a donor and each dopant which is an acceptor, while the energy transfers between dopants are efficiently blocked.
