Organic photodetectors have attracted considerable attention owing to the advantages they offer in terms of large-area processability, flexibility, adjustable spectral response range, low cost, and light weight. They play an active role in intelligent monitoring,communication, biomedicine, image sensors, and fluorescence microscopy. Organic photodetectors can be classified into broadband and narrowband based on their spectral response ranges. This paper introduces the basic structure, working principles, and key performance parameters of organic photomultiplier detectors in detail. Subsequently, the latest progress in broadband and narrowband organic photomultiplier detectors in the research field is summarized,expounding upon their practical applications. Finally, future development prospects of broadband and narrowband organic photomultiplier detectors are discussed.
