Hydrogen in hybrid perovskites: Researchers identify the defect that limits solar-cell performance By James Badham Chris Van de Walle Researchers in the materials department in UC Santa Barbara’s College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells. Various possible defects in the lattice of what are known as hybrid perovskites had previously been considered as the potential cause of such limitations, but it was assumed that the organic molecules (the components responsible for the “hybrid” moniker) would remain intact. Cutt...

Nanotechnology Now Home > Press > Better solutions for making hydrogen may lie just at the surface The unique interactions between perovskite oxide, its changing surface layer, and iron species that are active toward the OER paves a new path for the design of active and stable materials, bringing us one step closer to efficient and affordable green hydrogen production. CREDIT Argonne National Laboratory Abstract: A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That's because, even though hydrogen is abundant, it must be der...

That's because, even though hydrogen is abundant, it must be derived from another substance that contains it -- and today, that substance is often methane gas. Scientists are seeking ways to isolate this energy-carrying element...
