  • Organic photosensitive devices comprising a squaraine containing organoheterojunction and methods of making same
    Patent number: 10374164
    Abstract: An organic photosensitive optoelectronic device comprising at least one Donor-Acceptor heterojunction formed from a squaraine compound of formula I: wherein each of Ar1 and Ar2 is independently chosen from an optionally substituted aromatic group. The organic optoelectronic device described herein may also comprise a Donor-Acceptor heterojunction that is formed from at least two different squaraine compounds. A method of making the disclosed device, which may include at least one sublimation step for depositing the squaraine compound, is also disclosed.
