Efficiency increase of organic solar cells with emissive light-in-coupling layers
Top-absorbing organic solar cells with a light incoupling layer allowing the exposure of harmful UV irradiation have been fabricated. Short-wavelength light is absorbed by the down-shifting system Alq 3 :DCM located in the light incoupling layer of top-absorbing organic solar cells and is converted...
