Efficiency increase of organic solar cells with emissive light-in-coupling layers

Author affiliations

Abstract

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 Alq3:DCM located in the light incoupling layer of top-absorbing organic solar cells and is converted into longer wavelengths. This red light is then absorbed by a ZnPc:C60 bulk heterojunction solar cell, showing a total power efficiency increase by more than 10% related to additional photocurrent generated by this architectural concept.
