80‐3: High‐Performance Organic Photodetectors with Buffer Layers Suitable for In‐Cell Fingerprint‐Sensing Display

In this paper, we investigated the impact of OLED common layers on the performance OPDs and proposed two interfacial buffer layers, which simultaneously boost the EQE by 87‐folds and suppress the dark current density by a factor of two. The introduced buffer layers are compatible with different EBLs and HBL/ETL materials, namely the buffer layers are universal Besides, a prototype fingerprint recognition display sensor is demonstrated
