Abstract
Organic photovoltaic cells exhibiting an ideal diode behavior with large fill factor (FF) are presented. It is demonstrated that the current-voltage characteristics can be well described using the equivalent circuit model that is also used for inorganic solar cells. Resistances associated with the cells and other diode parameters are extracted by fitting the experimental electrical characteristics using the equivalent circuit model. The effects of these parameters on FF are quantitatively described. Changes in these parameters under different illumination conditions are presented and compared to those occurring in inorganic pn-junction solar cells.
