A W-type series-connected dye-sensitized solar module (W-type DSC module) has a significant drawbackof current mismatch attributed to its structural characteristics. This drawback is caused by low perfor-mance of the back-illuminated cell resulting from light loss. In this study, we attempted to alleviate thisphenomenon by adjusting the TiO2thickness of the back-illuminated cell in a W-type DSC module. Todemonstrate this, modeling of the back-illuminated cell as a function of the TiO2thickness and simulationanalysis of the W-type DSC module were conducted. The modeling was implemented using the powerelectronic simulation tool on the basis of the coefficient extraction from experimental data and the sim-ple interpolation method. As a result, it was demonstrated that the performance of the back-illuminatedcell improves by adjusting the TiO2thickness, resulting in an improvement in the current mismatch bybalancing the current between neighboring cells.
