Dr. Zongtao Liu earned his doctorate in condensed matter physics from Sun Yat-sen University in 2022. His doctoral research focused on passivated contact solar cells and low-cost metallization technologies. In addition, he has three years of corporate work and internship experience, which gives him extensive knowledge of the development and manufacturing of crystalline silicon solar cells. He joined the Electronic and Interface Materials Lab funded by the International Postdoctoral Exchange Fellowship Program of Guangdong Province to conduct research on novel passivating contacts for high efficiency solar cells.
