초록

In a research on the practical dye-sensitized solar cell, a study on a large module have preference because module must be able to generate the proper current that is possible to convert electrically. So the parallel connection of dye-sensitized solar cells which outputs a large current easily is essential. However, there is a current loss in a paralle connection of dye-sensitized solar cells and the loss becomes larger according to increasing the number of parallel connection. In this study, we analyzed the cause of the current loss in the parallel connection by using the equivalent circuit analysis. One DSC used in this experiment had an active area $8cm^2$(4.62cm$\times$1.73cm) and it attained a conversion efficiency of 5.43% under 1 sun illumination ($P_{in}$ of 100 mW/$cm^2$) using a solar simulator.
