Latest Patents

Yook's latest patents demonstrate her pioneering approach. One of her notable inventions relates to materials for controlling the epitaxial growth of photoactive layers in photovoltaic devices. This patent describes ultrathin film material templating layers that enhance the performance of small molecule organic photovoltaic (OPV) cells. The patented electron-transporting material, hexaazatriphenylene-hexacarbonitrile (HAT-CN), serves as a templating material, promoting a vertical-standing morphology of donor materials like copper phthalocyanine (CuPc) when deposited onto surfaces like indium tin oxide (ITO) electrodes. As a result, devices incorporating HAT-CN have shown improvements in fill factor and short circuit current compared to those without this template, attributed to reduced series resistance and improved crystallinity of CuPc.

Another significant patent focuses on a highly efficient carbazole-based compound, aimed at addressing the limitations of conventional organic electroluminescent devices, such as thermal instability and low efficiency. The invention utilizes a carbazole-based phosphine oxide compound, allowing for superior efficiency in pure-blue phosphorescent devices, marking a significant advancement in organic electroluminescence technology.
