  • NARROW BANDGAP NON-FULLERENE ACCEPTORS AND DEVICES INCLUDING NARROW BANDGAP NON-FULLERENE ACCEPTORS
    Publication number: 20190157581
    Abstract: Organic devices comprising an organic semiconducting acceptor motif coupled to a donor motif. Examples include IOTIC-2F, ITOTIC-2F, COTIC-4F, and SiOTIC-4F as acceptor materials. The acceptor materials have narrow bandgap (1.1 eV-1.3 eV), strong near-IR absorption and high solar cell EQE in near infrared (IR) region. The acceptor materials may also be used as the absorbing/light sensitive region in an IR photodetector.
