제목 | Enhanced Electron Life Time of Dendritic Photo-sensitizers in Dye-sensitized Solar Cells. |
초록 | Dye-sensitized solar cell (DSSC) has attracted much attention due to their high performance and easymanufacturing process. Many kinds of organic dyes (Metal-Free dyes) have been investigated as a photosensitizer in Dye-sensitized solar cell (DSSC) to increase the photovoltaic performance of the DSSC. The mechanism of DSSC is based on the injection of electrons from the photosensitizers into the conduction band of nano-crystalline TiO2 or ZnO. The oxidized photosensitizers are reduced by the electron injection from electrolyte. In this paper, we have studied on synthesis and characterization of dendritic organic dyes with different number of electron acceptor / anchoring moieties in the end of dendrimer. The photovoltaic performances and the incident photon-to-current (IPCE) of these dyes were measured to evaluate the effects of the dendritic strucuture on the open-circuit voltage and the short-circuit current. |
