Simple single‐layered diodes based on a glass‐forming triphenylamine‐thienylenevinylene with internal charge transfer show a photovoltaic effect in solar light and red electroluminescence when forward biased (see figure and cover). The use of an additional layer of C 60 as electron acceptor improves the photovoltaic performance without affecting the electroluminescence.
