Research Interests

​Stefaan De Wolf's expertise lies in the science and technology of photovoltaics for terrestrial applications. His research focuses on the fabrication of high-efficiency silicon-based solar cells, with specific attention to the fundamental understanding of interface structures and electrical contact formation, relevant to solar cells and electronic devices.

He is also interested in new device architectures and applications, such as back-contacted solar cells and silicon-based multi-junction solar cells, aimed at the improved utilization of the full solar spectrum for electricity generation. A prime example of these devices are perovskite-silicon tandem solar cells.
