Transparent conducting oxide free dye sensitized solar cell using flexible stainless steel mesh

We fabricated the dye-sensitized solar cells (DSCs) with new type of working electrode, which consisted of conductive and flexible stainless steel mesh sheet coated with 170 nm-thick TiO2 blocking layer deposited using various deposition techniques. Stainless mesh samples with blocking layer showed higher efficiency than those without a blocking layer. The best cell property in the present study showed the open circuit voltage of 0.58 V, short-circuit current density of 11.98 mA/cm2, fill factor of 0.45, and efficiency of 3.11%.
