Abstract

F-doped SnO2 nanowires array coated with carbon on stainless steel substrate was investigated as counter electrode (CE) for dye-sensitized solar cell (DSSC). With increasing the carbon coating time, the conductivities of F-doped SnO2 nanowires increased and the charge transfer resistances of the CEs decreased. The overall energy conversion efficiencies of DSSCs with an active area of 0.25 cm2 sensitized by a N719 dye reached up to 9.28% (AM1.5, 100 mW cm-2) by using the electrodes. It is found that the photovoltaic performance was deeply affected by the carbon coating time.
