Study of the Effect of Device Masking on Dye-Sensitized Solar Cell Electrical Parameters

The behavior of different masking percentages on the cell surface of the dye-sensitized solar cell (DSC) is investigated, and their effects on the various output parameters are described in detail based on the realistic equivalent circuit of the partial masking DSC. An increase in both current density and fill factor was observed with more masking percentages, and a reversed behavior was observed in the cell voltage. We identify factors that contribute to measurement errors and propose optimal conditions for getting more accurate results.
