|標題:||A Compact Nano-TiO2 Underlayer forEfficient Dye-Sensitized Solar Cell||關鍵字:||Electrodes;energy conversion;photovoltaiccells;titanium (Ti)||Project:||IEEE ELECTRON DEVICE LETTERS, Volume34, Issue 11, Page(s) 1415-1417.||摘要:||
A compact nano-TiO2 underlayer is formed on atitanium (Ti) foil through a two-step H2O2 + NaOH soakingpretreatment. This underlayer effectively suppresses thecharge recombination reaction on the photoanode side, whichis attributed to efficient electron transfer due to good adhesionbetween Ti and nano-TiO2. It also enhances the electricalcontact with screen-printed TiO2 mesoporous film due to surfacenanostructure. Both fill factor and short-circuit current densityare improved, and accordingly the power conversion efficiencyof dye-sensitized solar cell is enhanced by 22%.
