DEVICES INCLUDING ORGANIC MATERIALS SUCH AS SINGLET FISSION MATERIALS

摘要

Embodiments described herein relate to devices containing photoactive materials that, in some cases, undergo singlet fission. In some cases, the devices (e.g., solar cells) can efficiently convert photonic energy into usable electricity, with external quantum efficiencies greater than 100% in the visible region.

1. A device, comprising:
a donor material comprising an optionally substituted polyacene species or an optionally substituted polyene species; an acceptor material having a first side in physical contact with the donor material, and a second, opposing side; and at least one electrical contact in physical contact with the second, opposing side of the acceptor material, wherein the donor material is not in physical contact with an electrical contact.
