Abstract: A method for manufacturing a transparent counter electrode of a dye-sensitive solar cell is provided to adjust a concentration of platinum nano particles by controlling a process time and a current amount of an electro-reduction process. An electrolyte solution containing platinum ions is provided(110). The electrolyte solution is placed in an electro-chemical reactor(140) with a transparent conductive substrate(120) and a counter electrode(130). Negative and positive voltages are applied on the transparent conductive substrate and the counter electrode, respectively, by using a DC voltage supply(150), such that platinum ions are decreased in the conductive substrate. Voltage/current density and application timing are adjusted, such that the platinum particles are formed in an island shape and the counter electrode has a transparent property.
