Abstract
Abstract A new 2-methoxy-4,6-bis(4-(4-nitrostyryl)phenyl)nicotinonitrile (W-NO2) has been synthesized and the photovoltaic performances in dye‐sensitized solar cells (DSSCs) are investigated by utilizing it as co-sensitizer dye. From the study, its molar extinction coefficient value is found to be much higher than the N719 and the co-sensitized DSSC device showed a 1.78 times better efficiency than the N719 based devices. Preliminary DSSC results also revealed that the molecular architecture of dye (W-NO2) can be effectively utilized as a co-sensitizer along with the N719 to increase the spectral coverage as well as to achieve improved efficiency.
