50_49/2011Cover Picture: Low-Cost Copper Zinc Tin Sulfide Counter Electrodes for High-Efficiency Dye-Sensitized Solar Cells (Angew. Chem. Int. Ed. 49/2011)

A novel environmentally friendly Pt-free counter-electrode (CE) for dye-sensitized solar cells (DSSCs) based on low-cost quaternary copper zinc tin sulfide (CZTS) nanocrystals is described by Z. Lin and co-workers in their Communication on page 11 739 ff. CZTS nanocrystals were synthesized and spin-coated onto fluorine-doped tin oxide glass. After selenization of the CZTS semiconductor, the power conversion efficiency of the resulting DSSC was comparable to that of the device with a Pt CE.
