NOVELTY - A stacked organic photovoltaic battery comprises transparent substrate (1), transparent electrode (2), two semiconductor layers (3, 4) of first battery, three intermediate electrode layers (5-7), two semiconductor layers (8, 9) of second battery, and metallic electrode (10). The three intermediate electrode layers form an intermediate electrode that connects the first battery with the second battery.    USE - Stacked organic photovoltaic battery.    ADVANTAGE - The use of triple-layer organic heterostructure film as intermediate electrode avoids the quench of photoproduction exciton caused by introduction of granular metal, enables effective electron-cave compounding at the heterostructure interface and has no energy loss. Better electrical contact decreases internal resistance compared with the organic optical active layer, thus improving battery efficiency.
