On The Scalability of Dye-Sensitized Solar Cells : Effect of Photoelectrode Area on the Photovoltaic and Charge Transport Parameters

This study is aimed to provide new insights on the scalability of dye-sensitized solar cells (DSCs). The DSCs of electrode area up to ~2 cm2 were fabricated using commercially available P25 TiO2 particles, N3 dye, and iodide/triiodide electrolyte and evaluated using voltage - current and electrochem...
