Photomultiplication (PM) type all-polymer photodetectors (PM-APPDs) were fabricated by using polymer donor P3HT and acceptor PY-IT as the photoactive layers. An optimal weight ratio of to is approximately 100:4 achieve an efficient hole transport channel numerous isolated electron traps formed P3HT/PY-IT/P3HT. These active layers exhibit hole-only characteristics, resulting in a low dark-current density (JD) PM-APPDs. And JD PM-APPDs can be further suppressed employing triphenylamine-based cationic conjugated polyelectrolyte, TPAFA-7Br, layer (HTL) instead PEDOT:PSS layer. The with TPAFA-7Br HTL display rather 1.8 × 10–9 A·cm–2 under −10 V bias, which significantly lower than 2.1 10–6 for same bias. Additionally, external quantum efficiency (EQE) 1760% specific detectivity (D*shot) 0.9 1014 Jones at 630 nm 0.6 mW·cm–2 white light illumination. linear dynamic range 122 dB, exhibiting significant improvement compared 106 dB HTL. signal-to-noise optimized reaches 118,800 bias illumination, should among best values organic without additional current amplifier.
