Perovskite Photovoltaics and Optoelectronic Devices

Our group investigates perovskite-based photovoltaics and related optoelectronic devices from a fundamental, mechanism-driven perspective. Rather than focusing solely on performance metrics, our focus is aim to understand the physical processes that govern device functionality under realistic operating conditions.

We study single-junction and tandem photovoltaic architectures, as well as emerging multilayer device concepts, to uncover how charge generation, transport, recombination, and interfacial energetics collectively determine efficiency and energy yield. By combining materials synthesis, device fabrication, and advanced optoelectronic characterization, we establish quantitative relationships between material properties and device performance. 

Perovskite semiconductors provide a unique model system due to their strong light absorption, defect tolerance, and tunable bandgaps. At the same time, their dynamic nature challenges conventional semiconductor design principles.
