Ultra-Sensitive All-Polymer Near-Infrared Photodetectors via Van der Waals Layered Triple Heterojunction

Jones. To the best of our knowledge, this performance represents one of the best-reported all-polymer OPDs to date, providing a novel strategy for developing high-performance polymer-based photodetectors. Furthermore, we demonstrate the potential of LTHJ OPDs in optical integrated sensing and communications (O-ISAC) by achieving obstacle-penetrating optical wireless communication (OWC) and long-distance misalignment photoplethysmography (PPG) signal monitoring, further underscoring their applicability in next-generation intelligent sensing and complex communication environments.
