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.
