초록

A lot of researches and experiments have been performed to make more efficient dye-sensitized solar cell. Among them, insertion of a grid electrode in DSC is one method to increase overall performance as being shortened distance of electrons' movement by diffusion. In this paper, we measured overall characteristics which is included voltage-current characteristic curve, efficiency, fill factor by comparison between DSC without and with grid electrode. As a result, we got maximum 1.8 times increase of efficiency and approximately 1.7 times rise of fill factor. And we experimented 8, 10, 12, 14mm of grid gap and compared their results to optimize grid gap which is able to incite the most effective movement of electrons. Consequently, we got the result that electrons' movement is the most effect ive when grid gap is approximately 12mm.
