Abstract :
A compact nano- TiO2 underlayer is formed on a titanium (Ti) foil through a two-step H2O2+NaOH soaking pretreatment. This underlayer effectively suppresses the charge recombination reaction on the photoanode side, which is attributed to efficient electron transfer due to good adhesion between Ti and nano- TiO2. It also enhances the electrical contact with screen-printed TiO2 mesoporous film due to surface nanostructure. Both fill factor and short-circuit current density are improved, and accordingly the power conversion efficiency of dye-sensitized solar cell is enhanced by 22%.
