Efficiently cubic platinum-cobalt bimetallic nano-catalysts for use in low-cost dye-sensitized solar cells

Fuel-assisted polyol reduction for highly transparent and efficient Pt counter electrodes in bifacial dye-sensitized solar cells

“…The electrocatalytic activity of the CE was evaluated based on the peak current of Re-1 ( J Re-1 ), which is directly proportional to the diffusion coefficient of the redox couple, following the Randles-Sevcik theory. 12,[23][24][25] Furthermore, the potential difference between the oxidation and reduction peaks, known as peak-to-peak separation (DE), exhibits a negative correlation with the redox reaction rate. 12,26 Therefore, larger J Re-1 and smaller DE indicate a higher electrocatalytic activity of the CE.…”
