Polymer Solar Cells: Ultraflexible Polymer Solar Cells Using Amorphous Zinc−Indium−Tin Oxide Transparent Electrodes (Adv. Mater. 7/2014)

Polymer solar cells are fabricated on flexible, highly conductive, transparent amorphous zinc indium tin oxide (a-ZITO) electrodes by R. P. H. Chang, T. J. Marks, A. Facchetti and co-workers on page 1098. For two representative active layer donor polymers, the power conversion efficiencies (PCEs) are comparable with those of reference devices using polycrystalline indium tin oxide (ITO) electrodes. The new devices are highly flexible and can be repeatedly bent to a radius of 5 mm without significant PCE reduction.
