Light‐Emitting Organic Solar Cells Based on a 3D Conjugated System with Internal Charge Transfer

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 C60 as electron acceptor improves the photovoltaic performance without affecting the electroluminescence.
