Organic photosensitive devices with exciton-blocking charge carrier filters

Abstract

Disclosed herein are organic photosensitive devices including a first subcell and a second subcell and having at least one exciton-blocking charge carrier filter disposed between the subcells. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).
