Title: Young-Ho Choe and Thin-Film Solar Cell Innovation.
Introduction
Young-Ho Choe is an inventor associated with Seoul, South Korea, and LG Electronics Inc. His patent work concerns a nanoparticle-based ink for producing thin-film solar cells.
Latest Patents
Choe is associated with 1 patent: “Ink for Forming Thin Film of Solar Cells and Method for Preparing the Same, CIGS Thin Film Solar Cell Using the Same and Manufacturing Method Thereof.” The invention describes an ink containing copper selenide (CuSe) nanoparticles and indium-gallium selenide ((In,Ga)Seₙ) nanoparticles. The ink can be coated or printed onto a rear electrode and heated to form a light-absorbing layer containing copper, indium, gallium, and selenium.
The approach offers a way to produce copper indium gallium selenide (CIGS) thin films without vacuum processing or complex equipment. It also allows the film’s particle size and gallium concentration to be adjusted.
Career Highlights
Choe’s listed patent connects his work at LG Electronics Inc. with materials and manufacturing methods for thin-film solar cells. The invention focuses on simplifying CIGS layer formation through nanoparticle ink.
Collaborations
Yong-Woo Choi and Young-hee Lee are identified as Choe’s coworkers. The provided information does not specify their roles in the patent or the extent of their collaboration.
Conclusion
Young-Ho Choe’s patent highlights a practical nanoparticle-ink method for forming CIGS solar-cell layers, with the potential to simplify manufacturing and provide greater control over film composition.
