Abstract
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.
