High-sensitivity near-infrared organic photodetectors (NIR OPDs) have bright application prospects in the fields of optical communication, surveillance, chemical/biological detection and so on. In this review, we summarize recent works on NIR organic photodiodes and detail four main strategies: binary bulk heterojunctions (BHJs) with fullerene derivatives, binary BHJs with non-fullerene acceptors, ternary BHJs and a special kind of OPDs—visible blind NIR selective OPDs. Finally, based on the current development and challenges, we put forward the perspectives in this field.

用于近红外光检测的有机光电二极管

高灵敏度近红外有机光电探测器（NIR OPDs）在光通信，监视，化学/生物检测等领域具有广阔的应用前景。在这篇综述中，我们总结了有关近红外有机光电二极管的最新工作，并详细介绍了四种主要策略：具有富勒烯衍生物的二元本体异质结（BHJ），具有非富勒烯受体的二元BHJ，三元BHJ和一种特殊的OPD-可见的近红外NIR选择性OPD 。最后，根据当前的发展和挑战，提出了该领域的观点。
