Organic/inorganic hybrid phototransistors are a newly emerging class of advanced optoelectronic devices that possess remarkable sensing performance in a broad spectrum and are promising for large-area matrix integration and wearable applications. The rational customization of hybrid heterojunctions allows for extraordinary photoelectric behaviors and in-sensor computing functions. In this Spotlight on Applications, the recent progress and applications of organic/inorganic hybrid phototransistors in photodetection, sensor arrays, flexible electronics, and in-sensor computing are reviewed.
Organic/inorganic hybrid phototransistors are an emerging class of advanced optoelectronic devices. The separated organic high absorption layer and inorganic carrier transport layer endow hybrid phototransistors with remarkable sensing performance in a broad spectrum. The flexibility, ambient stability, and process compatibility of organic and metal oxide semiconductors also render them promising for large-area matrix integration and wearable applications. Moreover, extraordinary photoelectric behaviors, such as bidirectional photo responses and the versatility of in-sensor computing functions, including feature extraction and image enhancement, can be obtained by rational customization of the hybrid heterojunctions. In this Spotlight on Applications, we review the recent progress of organic/ inorganic hybrid phototransistors and their applications in photodetection, sensor arrays, flexible electronics, and in-sensor computing.
