Persistent internal photopolarization in C/sub 60/thin films: proposal for a novel fullerene-based solar cell Conference Paper uri icon

abstract

  • Abstract: We report on a persistent internal photopolarization effect observed in C/sub 60/thin films at room temperature. This differs from the similar" photoelectret" state previously seen in some other materials in that, unlike the latter, C/sub 60/does not undergo rapid photodepolarization. We suggest to utilize this phenomenon in fullerene-based heterojunction solar cells. A possible operating principle of such a device may combine the permanent built-in potential of a heterojunction with the repeatable photopolarization of a …
