Abstract
When a solar wavelength conversion material (solar spectral wavelength converter) produced based on a low-cost aluminum material having an ultraviolet ray absorption spectrum and a visible light emitting spectrum is positioned between a solar cell and an encapsulant of the front surface of the solar cell on which solar light is incident, photocurrent conversion efficiency of the solar cell may be improved by inducing a down-conversion effect and an anti-reflective coating effect at the same time, thereby increasing light-generated current.
