Prof. Sam Stranks Visited our group and delivered invited talk on “Halide Perovskite Semiconductors: From the Nanoscale to the Global Scale”

November 28, 2025

We were honored to host Prof. Sam Stranks from the University of Cambridge, a leading figure in energy materials and optoelectronics, as the 11th speaker in the Solar Energy Seminar Series (SES Series), in collaboration with the CeNS Colloquium.

Prof. Stranks is widely recognized for his pioneering work on emerging semiconductors, especially halide perovskites for next-generation photovoltaics, LEDs, and medical imaging. In addition to his professorship in Chemical Engineering & Biotechnology, he is a Cavendish Joint Member in Physics and a Fellow of Clare College. His scientific impact has been acknowledged globally through distinctions such as MIT Technology Review Innovators Under 35 and TED Fellowship, and he is the co-founder of the solar startup Swift Solar.

Invited by Dr. Erkan Aydin, Prof. Stranks delivered a talk titled
“Halide Perovskite Semiconductors: From the Nanoscale to the Global Scale”
at the NanoInstitute. In his lecture, he highlighted:

• Performance and stability challenges in state-of-the-art halide perovskite solar cells

• Multimodal microscopy approaches to uncover nanoscale defect landscapes

• Correlations between structural and carrier-trapping behavior that reveal degradation pathways

• Recent breakthroughs in vapour-deposited, epitaxial perovskites enabling clean interfaces and tunable electronic properties

During his visit, Prof. Stranks spent the morning at the Grosshadern Chemistry Campus and the afternoon at the NanoInstitute (city center), engaging in stimulating scientific discussions and participating in several lab tours.

We look forward to continuing our scientific exchange with Prof. Stranks and exploring future collaborations in advancing the fundamentals of perovskite optoelectronics.
