<p>A dye-sensitized solar cell includes a first electrode including a conductive transparent substrate; a light absorption layer disposed on a side of the first electrode; a second electrode facing the first electrode; and an electrolyte disposed between the first and the second electrode. The light absorption layer includes a porous membrane that includes semiconductor particulates, and a photosensitized dye adsorbed on a surface of the porous membrane. The porous membrane has a membrane density ranging from 0.83 to 1.97mg/mm3, wherein the membrane density is a ratio of a porous membrane volume relative to a semiconductor particulate mass.
