Here we study solution-processed semiconducting single-walled carbon nanotubes (SWNTs) and perovskite quantum dots(QDs) hybrid films for high-performance light detectors. Small diameter SWNTs are wrapped by conjugated polymer semiconductors and collected and used as semiconducting SWNTs networks for providing high charge transport characteristics in phototransistors. Although single components active layers only with semi-SWNTs and perovskite QDs show little changes in light absorption and photocurrent formation, hybrid films with bi-layer or bulk-heterojunction structures demonstrated higher light detection characteristics with more than 100 times larger photocurrent under the illumination of visible light in comparison to the same devices in the dark. Therefore, it is expected that a hybrid photo-active layer can be broadly used to develop high-performance light sensors for many applications, including image sensors and wearable healthcare.
