Huotian Zhang

During my doctoral study, I focused on the relation between fill factor and open-circuit voltage loss in organic solar cells. My current research interest is the physical process of photovoltaics and interfaces between organic molecules.

LiU researchers push the boundaries of organic solar cells

Researchers at LiU have now demonstrated how organic solar cells can become more efficient than previously thought possible. The key is to extend the time that electrons in the material remain excited, which leads to improved performance.

Huotian Zhang receives royal scholarship for his solar energy research

For the second year in a row, a researcher at the Division of Optoelectronics at Linköping University, has been awarded the prestigious scholarship from Stiftelsen Konung Carl XVI Gustafs 50-årsfond för vetenskap, teknik och miljö.
