Organic photosensitive devices with exciton-blocking charge carrier filters

Patent ·
OSTI ID:1472088
; ; ; ; ; ; ; ;
Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. 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 novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).
