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 o...

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 re...

Thats because, even though hydrogen is abundant, it must be derived from another substance that contains it -- and today, that ...

The Department of Energy in recent days announced two major initiatives that will put more than $75 million in projects that seek to make industry more efficient and advance carbon capture technology. Energy Secretary Jennifer Granholm announced $52.5 million toward industrial assessment centers (IACs), which use federal funds to research energy conservation in industrial settings."These programs are proof that big climate investments can help...

In a regulatory filing, Basic Energy said that the board directors of its wholly owned subsidiary Mabini Energy Corp. also greenlit the move for Oscar L. de Venecia, Jr., the parent firm’s president, to sign the service contract...

MANILA: Philippine stocks have rapidly gone from one of the world’s best performers to the absolute worst, prompting the nation’s growing pack of retail investors to shift attention to speculative penny stocks in the search for better returns. The Philippine Stock Exchange Index is down 7.4% so far this year, the biggest decline among 92 global equity benchmarks tracked by Bloomberg. That’s a dramatic turnaround after the gauge’s 22% surge in the three months ended December saw it ranke...
