Latest Patents
Lee’s patent portfolio includes inventions aimed at improving the conversion of light into usable energy.
- **Method for Improving Solar Energy Conversion Efficiency Using Metal Oxide Photocatalysts Having Energy Band of Core-Shell for Ultraviolet Ray and Visible Light Absorption and Photocatalysts Thereof.** This invention describes forming a nanoparticle thin-film layer, creating core-shell metal oxides through a plasma reaction under hydrogen and nitrogen, and depositing a transition metal on the nanoparticle surfaces. The core-shell structure creates oxygen vacancies in the shell, which can improve the transfer of light-excited electron-hole pairs. Its modified band-gap structure is also designed to extend light absorption into the visible range.
- **Method for Fabricating High-Efficiency Bio-Photovoltaic Cells by Using Plasmonic Silver Nanoparticles and Natural Extracted Graminoids.** This invention describes coupling graminoids extracted from natural grasses to a semiconductor electron acceptor using an organic ligand. Plasmonic silver nanoparticles are aligned on the electron acceptor to enhance photo-electron generation through a surface-plasmon effect. The approach also seeks to improve electron transfer by optimizing the bond between the photosensitizer and the electron acceptor.
Career Highlights
Lee’s patented work addresses two approaches to renewable-energy generation: enhancing photocatalytic conversion across ultraviolet and visible wavelengths, and developing bio-photovoltaic cells that use natural plant-derived materials.
