[Asia Economy Reporter Hyunju Lee] Sejong University announced on the 23rd that the research team led by Professor Donghoe Kim of the Department of Nano New Materials Engineering has succeeded in developing a technology that can overcome environmental regulations hindering the commercialization of perovskite solar cells. The research results were published in the online edition of the international journal Nature Sustainability. The research team focused on the treatment of lead waste generated during the recycling process of solar cells and the development of recycling processes. They developed an eco-friendly material composite of hydroxyapatite and iron nanoparticles, achieving lead removal efficiency that meets the lead concentration standards set by the U.S. Environmental Protection Agency.
