  "textContent": "A research team has developed a technology to precisely control the concentration of anion defects in eco-friendly quantum dots through joint research. Through this technology, the research team achieved world-class solar hydrogen production efficiency in the field of heavy-metal-free eco-friendly quantum dot photoelectrodes. The team was led by Professor Jiwoong Yang and Professor Su Il In from the Department of Energy Science & Engineering at DGIST, in collaboration with Professor Jae-Yup Kim from the Department of Chemical Engineering at Konkuk University. The paper is published in the journal eScience.",
