Abstract

original image

The frontispiece shows the wavy surface of a stretchable organic solar cell. The device was rendered stretchable by depositing the transparent electrode (a conducting polymer, PEDOT:PSS) and the active material (a conjugated polymer, P3HT, and a fullerene derivative, PCBM) on a pre-strained membrane, as reported by Zhenan Bao and co-workers on p. 1771. Release of the prestrain buckled the active layer. The device could be stretched up to 27%.
