Abstract
The present disclosure relates to a sunlight converting device including a wavelength converting film using a wavelength conversion material such as a quantum dot or an inorganic phosphor. More particularly, the present disclosure provides a sunlight converting device including a wavelength converting film using a wavelength conversion material, which can optimize plant growth and provide improved plant quality by installing a wavelength converting film on which a wavelength conversion material is applied so as to be converted into a predetermined wavelength and output to a greenhouse (glasshouse), a vinyl house or a microalga culture facility, varying the sunlight irradiation area of the wavelength converting film, and supplying light of various wavelengths required for species of plant including microalgae or growth cycles thereof.
