Tailoring a Back‐Contact Barrier for a Self‐Powered Broadband Kesterite Photodetector With Ultralow Dark Current Enabling Ultra‐Weak‐Light Detection

Tailoring a Back‐Contact Barrier for a Self‐Powered Broadband Kesterite Photodetector With Ultralow Dark Current Enabling Ultra‐Weak‐Light Detection

ABSTRACT Visible and near‐infrared photodetectors are widely used in intelligent driving, health monitoring, and other fields. However, the application of photodetectors in the near‐infrared region is significantly impacted by high dark current, which can greatly reduce their performance and sensiti...
