PURPOSE : A dye sensitized solar cell which includes a quasi-solid polymer electrolyte, a wavelength conversion rare earth material, and a hole conductive ball absorbent is provided to reduce electron recombination in the interface of an electrolyte which include iodine and a semiconductor layer, thereby improving photo voltage and photo current of the solar cell. CONSTITUTION : A light absorption layer is formed on one side of a first electrode. The light absorption layer comprises a ball absorbent which has hole conductive properties and a wavelength conversion rare earth material. A second electrode is arranged to face one side of the first electrode. A quasi-solid polymer electrolyte is located in the space between the second electrode and the first electrode. The quasi-solid polymer electrolyte comprises a hole transfer material. COPYRIGHT KIPO 2012
