High Performance Polarization-Resolved Photodetectors Based on Intrinsically Stretchable Organic Semiconductors.

ABSTRACT: Polarization-sensitive photodetectors based on anisotropic semiconductors sense both the intensity and polarization state information without extra optical components. Here, a self-powered organic photodetector (OPD) composed of intrinsically stretchable polymer donor PNTB6-Cl and non-fullerene acceptor Y6 is reported. The PNTB6-Cl:Y6 photoactive film accommodates a remarkable 100% strain without fracture, exhibiting a high optical anisotropy of 1.8 after strain alignment. The resulting OPD not only shows an impressive faint-light detection capability (high spectral responsivity of 0.45 A W^-1 and high specific detectivity of 10¹² Jones), but also has a high anisotropic responsivity ratio of 1.42 under the illumination of parallel and traversed polarized light.
