Stable organic photosensitive devices with exciton-blocking charge carrier filters utilizing high glass transition temperature materials
Patent
·
OSTI ID:1568279
Disclosed herein are stable 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 having a sufficiently high glass transition temperature, e.g., higher than the temperature or temperature range at which the device typically operates, higher than a highest operating temperature of the device, higher than a threshold temperature value, etc. 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).
