Abstract

A new platinum acetylide complex, (3-(4-(diphenylamino)phenylethynyl))(3-(4-(2-carboxyl-2-cyanovinyl)phenylethynyl))(bis(triethylphosphine))platinum (Pts), has been designed and synthesized as a sensitizer for application in dye-sensitized solar cells (DSSCs). The absorption spectra, electrochemistry, impedance spectroscopy and photovoltaic properties of this platinum acetylide complex have been extensively investigated. For the best DSSC, the overall solar-to-electric conversion efficiency of 3.28% was achieved with a short-circuit photocurrent density (Jsc) of 6.77 mA cm−2 and the open-circuit photovoltage (Voc) of 0.70 V(fill factor ff = 0.69).
