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. To the best of the authors’ knowledge, both the detector performance and polarization features are among the best-performing OPDs and polarization-sensitive photodetectors. As a proof-of-concept, polarization-sensitive OPDs are also utilized to set up a polarimetric imaging system and full-Stokes polarimeter. This work explores the potential of highly stretchable organic semiconductors for state-of-art polarization imaging and spectroscopy applications.

基于本质可拉伸有机半导体的高性能偏振分辨光电探测器
基于各向异性半导体的偏振敏感光电探测器无需额外的光学元件即可感测强度和偏振态信息。在此，报道了一种由本质上可拉伸的聚合物供体 PNTB6-Cl 和非富勒烯受体 Y6 组成的自供电有机光电探测器（OPD）。 PNTB6-Cl:Y6 光敏薄膜可承受显着的 100% 应变而不会断裂，在应变排列后表现出 1.8 的高光学各向异性。由此产生的 OPD 不仅表现出令人印象深刻的微光探测能力（0.45 AW -1的高光谱响应度和 10 12 Jones 的高比探测率），而且在平行和横向偏振照明下具有 1.42 的高各向异性响应比光。据作者所知，探测器性能和偏振特征均属于性能最佳的 OPD 和偏振敏感光电探测器。作为概念验证，偏振敏感 OPD 还用于建立偏振成像系统和全斯托克斯偏振计。这项工作探索了高度可拉伸有机半导体在最先进的偏振成像和光谱学应用中的潜力。
