Cover Picture: Light-Emitting Organic Solar Cells Based on a 3D Conjugated System with Internal Charge Transfer (Adv. Mater. 22/2006)
The cover image illustrates the dual photovoltaic and electroluminescence function of a single-layer device based on a thienylenevinylene–triphenylamine with internal charge transfer (ICT), as reported by Cravino, Roncali, and co-workers on p. 3033. The material forms an organic glass with isotropic electronic properties while ICT leads simultaneously to an extension of the photoresponse to the red and to an increase of the open circuit voltage. The use of an additional layer of C60 further improves the photovoltaic. Images of the sun and moon courtesy NASA/JPL–Caltech.
