제목 Desirable multiple functioned coadsorbents for highly efficient DSSC
초록 Novel multi functioned coadsorbents (HC-Acids) have been systematically developed to use as an alternative to deoxycholic acid (DCA) in organic dye-sensitized solar cells (DSSCs). HC-A series has multiple functions, such as the light-harvesting function as short-wavelength light absorption dye molecule to increase Jsc, the prevention effect of the π-πstacking of organic dye to enhance Voc by reducing the charge recombination, and the hole conducting function to enhance dye regeneration. As a result, the photovoltaic performance of HC-A3 and HC-A4 devices exhibited a remarkably high Jsc, 16.94 mA/cm2, Voc of 0.679V, FF of 0.75, of 8.63% at 100 mW cm-2(HC-A4), and Jsc, 15.84 mA/cm2, Voc of 0.719V, FF of 0.75, of 8.55% at 100 mW cm-2(HC-A3).
