  • Patent number: 9985230
    Abstract: The present invention is related to a process for reducing surface energy of a hole transport layer. The disclosed process comprises providing a hole transport layer; and providing a fluorine-containing layer directly on said hole transport layer. The configuration of said fluorine-containing layer reduces the structural disorder of an active layer and is able to recover a moisture-degraded hole transport layer, and thereby improves the performance of an electric device containing the same.
