제목 Enhanced Performance of Dye Co-sensitized Solar Cells prepared from the  One-bath Mixed Dye Solution Process.
초록 There has been an increasing interest in the dye sensitized solar cell (DSSC) owing to a potential for highly efficient solar energy-to-electricity conversion efficiency, low-cost and easy manufacturing process. It was known that solar energy conversion efficiencies of DSSC are strongly dependent on dye molecules absorbed on the TiO2 surface which used for photosensitization of sun light, since an excited state of dye could inject an electron into the conduction band of semiconductor. In this paper, we designed and synthesized a series of organic photosensitizers containing long wavelength absorbing chromophore for the DSSC. The organic dyes containing squaraine chromophore could absorb long wavelength region which could be strong candidates for the Blue/NIR sensitizers for the DSSC. The photovoltaic properties and the incident photon-to-current efficiencies of DSSCs containing long wavelength absorbing organic chromophores were measured and evaluated by comparison with that of individual chromophores.
