An organic photovoltaic (OPV) device is provided. The OPV device comprises at least one photovoltaic layer, said layer comprising a mixture comprising at least one diketopyrrolopyrrole (DPP) polymer and at least one stabilizer, wherein the stabilization The agent is selected from the group consisting of UV absorbers and anti-radical agents. The mixture comprising at least one stabilizer, preferably a UV absorber or an anti-radical agent, and at least one DPP polymer is used to increase the product life of the OPV device and at least one DPP polymer. Can be used to prevent decomposition during the manufacture of OPV devices. |
