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