Lead-free quantum-dot photodetectors (QPDs) are currently the subject of research interest
due to the environmental threat posed by lead, but relatively poor photodetection ability has
been reported so far. Here, we develop high-performance AgBiS 2 nanocrystal (NC)-based
QPDs with a responsivity (R) of 0.55 A/W and detectivity (D*) of 1.4× 10 12 Jones at− 0.5 V
under a 680 nm LED light (1.0 mW/cm 2) by incorporating a novel conjugated polyelectrolyte
(CPE) as a cathode buffer layer (CBL) on the surface of the electron transporting layer (ETL) …
