A More Efficient Organic Photovoltaic Cell with Enhanced Performance


Background: Although there have been several proposed alternative materials for organic photovoltaic cells organic photovoltaic cells are comparatively inefficient to silicon-based photovoltaic cells. UCF researchers have developed a new more effective and efficient way of organic materials for the organic photovoltaic cell. Specifically this invention involves an organic photovoltaic material comprised of a bulk heterojunction (BHJ) composition of poly(3-hexylthiophene) (P3HT) and [66]-phenyl C61 butyric acid methyl ester (PCBM) often referred to as P3HT:PCBM BHJ providing improved performance. This organic photovoltaic cell structure provides a work function in the nickel and indium doped tin oxide material anode in the range of -5.0 to -5.4 eV thereby providing enhance hole extraction. Technology Description: This invention uses a nickel and indium doped tin oxide material layer as an anode to increase the work function of the anode for P3HT:PCBM BHJ organic photovoltaic cells. This invention’s chemical composition provides enhanced hole charge carrier extraction transport and collection within an organic photovoltaic cell device that derives from the organic photovoltaic cell structure. The P3HT:PCBM BHJ composition can be used in multiple applications within non-limiting organic photovoltaic cell structures. Applications: 1) solar energy 2) solar panels 3) electronics 4) windows
