Abstract
Provided is a solar cell including: a first electrode and a second electrode facing each other; a porous membrane interposed between the first electrode and the second electrode and having a dye adsorbed thereto; an electrolyte interposed between the first electrode and the second electrode; and a buffering layer interposed between the first electrode and the porous membrane and having at least two layers. According to the construction of the solar cell, an electron-hole recombination is prevented by preventing the contact between an electrode having a porous membrane and an electrolyte, thereby improving the electron collection property and the photoelectric conversion efficiency of the dye-sensitized solar cell.
