1. A thin film for a photoelectric device, the thin film comprising:
a first charge transport material and a second charge transport material that collectively define a heterojunction,
wherein the thin film is configured to facilitate transfer of charge carriers that are separated in a photoelectric conversion layer of the photoelectric device to reduce a quantity of remaining charge carriers in the photoelectric conversion layer, and
wherein the first charge transport material and the second charge transport material are mixed, and
wherein the first charge transport material and the second charge transport material have a same nitrogen-containing ring.
