NOVEL COMPOUND AND USE THEREOF AS A HOLE-TRANSPORT MATERIAL

摘要

The present invention provides novel triazatruxene derivatives that can be used as hole-transport materials (HTM), particularly in optoelectronic devices. The usefulness of the novel compounds in solid-state sensitised solar cells based on organic-inorganic perovskites, which are used as light capturers, has been confirmed. The devices have achieved high energy conversion efficiency.
