Abstract
• Novel low bandgap conjugated polymer was synthesized. • The polymer exhibited absorption up to 950 nm. • Near-infrared photodetectors based on polymer-fullerene blends were created. • Photodetectors demonstrated fast photoresponse at zero external bias. A low bandgap conjugated polymer comprising benzodithiophene and diketopyrrolopyrrole units was designed and synthesized. The polymer showed an optical bandgap of ~1.3 eV and exhibited broad absorption in visible and near-infrared spectral ranges. Photodetectors based on the polymer/fullerene derivative blends were fabricated and their electrical behavior was investigated. The devices demonstrated rapid response in the infrared (λ = 850 nm) wavelengths. Photodetectors can be operated in up to 2.6 × 10 5 Hz frequency regime with responsivity of 42 mA W - 1 and detectivity of 1.26 × 10 12 Jones at λ = 850 nm and zero external bias.
