Dye Sensitized solar cells (DSSC) are a significant stepping stone in the field of photovoltaics . In DSSCs, a blocking layer is generally used in between the conducting electrode and the porous titanium dioxide layer. A compact blocking layer covers the rough surface of anode and reduces the probability of short-circuits between the electrolyte and the photoanode.

However, a thick blocking layer can also act as a resistance. Therefore, efficient cells require a careful optimization of its thickness. In the present work, a compact blocking layer has been optimized for DSSCs based on a quasi solid state electrolyte and Eosin B as the sensitizer material.

The porous semiconductor oxide layer and the optimized compact blocking layer have been characterized by scanning electron microscopy. In addition, the functionality of the blocking layer in DSSC is verified by solar cell characterizations. A significant enhancement has been obtained in DSSCs with blocking layer as compared to the reference cell.
