Hello! I’m Dr. Yiying Wu, professor of chemistry and biochemistry at THE Ohio State University, and with me are doctoral students Mingzhe Yu and Billy McCulloch. We want to make solar energy a reality for the power grid. We work at the intersection of synthetic inorganic chemistry, materials chemistry, and photoelectrochemistry to create devices that are hybrids of solar panels and batteries: “solar batteries.” So far, we’ve invented a solar air battery (a “breathing” battery that releases oxygen when it’s charged by sunlight) and an aqueous solar flow battery (which has an eco-friendly water-based electrolyte circulating in it). We’ve seen you discuss our work on r/science, and we will be back at 1pm ET to answer your questions, ask us anything!

But these questions can inspire us to think beyond the scientific questions to the larger issues.
