Latest Patents

One of Gumin Kang's latest patents is a luminescent solar concentrator with phosphor-doped polymer resin. This invention relates to a transparent luminescent solar concentrator (LSC) that includes a polymer resin panel uniformly doped with phosphors. This design greatly improves the transmittance and optical haze compared to existing LSCs. Additionally, it enhances the light collection efficiency through the arrangement of solar cells embedded in the polymer resin panel. The panel can be manufactured with flexibility or rigidity, allowing for applications in curved structures such as building windows, automobile glasses, and greenhouse roofs.

Another notable patent is focused on down-shifting nanophosphors, a method for preparing them, and a luminescent solar concentrator utilizing these nanophosphors. This invention includes a core made of NaYF nanocrystals doped with neodymium (Nd) and ytterbium (Yb), surrounded by a neodymium-doped crystalline shell. These down-shifting nanophosphors efficiently absorb near-infrared rays and emit them in a specific wavelength range. Their small size allows for easy application in the manufacture of transparent LSC films, contributing to the development of transparent solar cell modules with high near-infrared ray shifting efficiency.
