Abstract: Provided is a wavelength converting structure for near-infrared rays and a solar cell using the same. More particularly, provided is a novel wavelength converting structure for near-infrared rays using gap plasmon characteristics and up-conversion nanoparticles. When applying the wavelength converting structure for near-infrared rays to a solar cell, it is possible to convert the light within a wavelength range of near-infrared rays into electric energy so that the photoconversion efficiency may be improved.
