Abstract |
Recently, a study on the energy conversion efficiency and up sizing' technology of dye-sensitized solar cell (DSC) which is focused in considering a new alternative solar cell has been executed. But consideration for the cell characteristics about an internal electronic flow on a large-scaled DSC has not been carried out yet. In this study, we have chosen a solar cell width as a variable of a large-scaled DSCs and confirmed electric characteristics of an individual cell. First, Pt counter electrode surface of DSC is deposited by RF sputtering methode and the electrochemical properties of Pt electrodes was investigated by cyclic -voltammetry. With the Pt electrode, we fabricated DSC samples of different width. As a result, the higher the internal resistance of DSC becomes, the wider the width gets. Internal resistance makes it difficult to collect photoelectron generated from dye. Ultimately up sizing DSC causes the increase of internal resistance and then has a bad effect on the cell characteristics. |
