Single crystals of a silver/organic charge-transfer complex are doped by illumination via optical fibers (see Figure). Continuous illumination with UV–visible light induces electron transfer between the organic π-acceptor and a silver ion in the organic charge-transfer complex in the solid state. Illumination of one half of a single crystal produces a p–n junction rectifier in a single step.
