The OneChemistry Symposium, organized by Prof. Rigoberto Hernandez (Johns Hopkins University Department of Chemistry), brought together the SPIRAL team comprising researchers from the University of Virginia, Cornell University, Johns Hopkins University, Pacific Northwest National Laboratory (PNNL), National Renewable Energy Laboratory (NREL), and the University of Michigan to discuss the future of solar cell research. The focus of the discussion was on perovskite solar cells, and participants shared ideas and discussed collaborations to drive research forward. The event was a two-day affair held with guest lectures and panel discussions featuring both theoretical and experimental perspectives. Overall, the event was a great opportunity for researchers to exchange ideas and make progress towards the next generation of solar cells.
