摘要： Provided are a dye-sensitized solar cell and a method of manufacturing the same, which includes: a lower electrode formed of a titanium metal or a titanium alloy; a titanium oxide electrode having a nanotube structure formed on the lower electrode; a metal oxide layer formed on the titanium oxide electrode along a step difference of the nanotube, having a larger band gap than titanium oxide, and having a dye adsorbed on a surface thereof; a counter electrode spaced a predetermined distance apart from the metal oxide layer; and an electrolyte filled between the metal oxide layer and the counter electrode. The titanium oxide electrode having a nanotube structure, which has a large specific surface area, may increase absorption of solar light and allow easy adsorption of a dye due to the metal oxide layer, thereby improving photo current and voltage characteristics of the solar cell.
