Estimating the term…
The present invention relates to a dye-sensitized solar cell and to a method for manufacturing same, and more specifically, provides a novel dye-sensitized solar cell for preventing photoelectron recombination due to a triiodide, and to a method for manufacturing same. The dye-sensitized solar cell, according to the present invention, comprises a metal oxide resulting from coadsorbing, on a surface of the dye-sensitized solar cell, a reactive compound which can react with iodine with a dye. The dye-sensitized solar cell is highly efficient by being able to prevent the photoelectron recombination due to the triiodide while using a small amount of the dye.
A dye-sensitized solar cell, comprising a semiconductor electrode, a counter electrode and an electrolyte, wherein the semiconductor electrode is configured such that a dye is adsorbed on a porous thin film including an oxide semiconductor and an ion layer is formed thereon.
A dye-sensitized solar cell, comprising:
An oxide semiconductor electrode configured such that a compound which is coupled with a halogen of an electrolyte to form a halogen ion layer is adsorbed on a surface thereof.
A method of manufacturing a dye-sensitized solar cell, the method comprising:
A method, comprising forming an ion layer on a surface of a metal oxide semiconductor layer so that contact between a metal oxide semiconductor and an oxide is prevented, in order to increase efficiency of a solar cell.
