Abstract

The effects of push-pull porphyrin dyes as well as copper(I/II) redox shuttles on photovoltaic properties have been examined toward high-performance dye-sensitized solar cells (DSSCs). DSSC with a combination of porphyrin dye LG4 and bis(4,4′,6,6′-tetramethyl-2,2′-bipyridyl)copper(I/II) exhibited the highest power conversion efficiency of 5.07% ever reported for porphyrin-based DSSCs using copper(I/II) redox shuttles.
