Change of Dye Bath for Sensitisation of Nanocrystalline Films: Enhances Performance of Dye-Sensitized Solar Cells

The photovoltaic performance of the heteroleptic H 102 and HRD 2 sensitizers was measured in DSSC and compared with that of reference N719 under similar fabrication and evaluation conditions. The Dye-Sensitised TiO 2 electrodes were prepared by staining the electrodes in ethanol bath and 1/1 v/v ace...

Description
Summary:The photovoltaic performance of the heteroleptic H 102 and HRD 2 sensitizers was measured in DSSC and compared with that of reference N719 under similar fabrication and evaluation conditions. The Dye-Sensitised TiO 2 electrodes were prepared by staining the electrodes in ethanol bath and 1/1 v/v acetonitrile/ tert -butanol (binary liquid) mixture bath separately and the DSSCs based on these sensitizers show that the change of dye bath from ethanol to the binary liquid mixture enhances the photocurrent action spectrum and solar-to-electricity conversion efficiencies, ( η ). Using ethanol for sensitisation of TiO 2 electrodes, the efficiencies obtained for H 102, HRD 2 and N719 are 4.31%, 4.62%, and 5.46%, respectively, while in binary liquid mixture bath, the corresponding values are enhanced to 5.89%, 4.87%, and 7.23%, respectively, under comparable conditions.
