  • THERMALLY ACTIVATED DELAYED FLUORESCENCE (TADF) MATERIALS FOR HIGH EFFICIENCY ORGANIC PHOTOVOLTAICS
    Publication number: 20250133955
    Abstract: Described are organic photovoltaic devices comprising an anode; a cathode; and a photoactive organic material in a layer disposed between the anode and the cathode, the energy difference between the triplet energy state (T1) and the singlet energy state (S1) (?EST) in the photoactive organic material is less than about 300 meV; and when the organic photovoltaic device is illuminated with light having an AM1.5 spectrum, the organic photovoltaic device has an open circuit voltage of greater than 0.9 V, a power conversion efficiency of greater than 22%, and an EL external quantum efficiency >5%.
