The p-n junction photodiodes have widely utilized in solar cells and image sensors, and the high-efficiency photodiodes are achieved by the suppression of leakage current and charge recombination and the improvement of photo-induced charge collection. In this study, the conjugated polyelectrolytes and high dipole small molecules were designed and synthesized to improve the photo-induced current density and reduce the dark current density in the devices as a cathode buffer layer. The synthesized cathode buffer layer materials was coated on the electron transporting layer (ETL), which dramatically enhanced the photodiode properties via modifying the work function of the ETL and improving the surface contact properties between ETL and active layer. The detailed discussion will be given in the presentation.
