Photovoltaic and Photomultiplication Dual‐Mode Near‐Infrared Organic . . . In this study, a photovoltaic photomultiplication dual-mode organic photodetector is developed by integrating two different organic bulk heterojunctions (BHJs), one introduces the photovoltaic effect, and the other triggers photomultiplication charge generation in the stacked device at different voltage polarities
Bias-Switchable Photomultiplication and Photovoltaic Dual-Mode Near . . . This study presents the synthesis and incorporation of a non-fullerene acceptor, BFDO-4F, into the active layer to introduce trap states for capturing photogenerated electrons The resulting device exhibits dual-mode characteristic and is bias-switchable between PV and PM-modes
Organic photodiodes with bias-switchable . . . - Nature We design the OPD to operate in PM-mode under forward bias by introducing thermal-induced interfacial structural traps, which can tune the trapped carrier type by bias direction; and retain the
Photovoltaic and Photomultiplication Dual‐Mode Near‐Infrared Organic . . . The ultra‐low noise level of the photovoltaic mode enables it to detect faint light with exceptional sensitivity, while the photomultiplication mode can handle a significantly large saturation photocurrent, allowing for the precise detection of high‐intensity signals

Photomultiplication‐Type Organic Photodetectors for Near‐Infrared . . . Here, we report a fully vacuum-processed PM-OPD with a spectral response spanning from the ultraviolet (UV) to the near-infrared (NIR) region (300–900 nm) Based on a low donor content (4 0 wt%) in the BDP-OMe:C 60 material system, the device shows an EQE beyond 100% at a rather low bias of −1 V, leading to a D* above 10 13 Jones
