Mission Our lab seeks to transform the way we produce and consume energy as a society, by exploiting the exceptional properties of emerging soft semiconductors. For this, we explore the concept of symmetry breaking in novel soft semiconductors and nanomaterials to control charge, spin and light with these printable materials.We work on uncovering the design rules to enable the next generation of cheap and flexible solar cells & ultra-bright displays, and unlock entirely new applications in quantum information technology, all with the overarching goal of maximizing energy conversion efficiency.

Physical Chemistry Seminar 1: Trends CH-643 Students can learn about the broader research in Phyiscal Chemistry and broaden their horizon beyond their own field by listening to 14 talks by speakers presenting their recent research. The students get the opportunity to also personally meet the speakers and discuss research topics.
