Boosted photocatalysis for hydrogen evolution: Reactant supply thru phosphonate groups

(Shinshu University) Water splitting research for solar hydrogen production has focused on physical processes inside the semiconductor, such as light absorption, charge separation, and chemical processes on the surface that are highly complex and rely on the development of new materials. The concept proposed in this study is design of the electrolyte-photocatalyst interface. The approach of immobilizing functional groups near the solid-liquid interface can be a broad-ranging methodology that is effective regardless of the materials used.

Greenland melting likely increased by bacteria in sediment

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to new study. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.

Key features that help block excess light absorption during photosynthesis

New research reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae — including key features that both collect energy and block excess light absorption. Scientists built a model of the large protein complex called phycobilisome that collects and transmits light energy. Phycobilisomes allow cyanobacteria to take advantage of different wavelengths of light than other photosynthetic organisms. The study yields insights relevant to future energy applications.

On the road to invisible solar panels: How tomorrow’s windows will generate electricity

Researchers demonstrate the first transparent solar cell. Their innovative technique rests on a specific part of the solar cell: the heterojunction, made up of thin films of materials responsible for absorbing light. By combining the unique properties of titanium dioxide and nickel oxide semiconductors, the researchers were able to generate an efficient, transparent solar cell.

Using solar energy and agriculture to limit climate change, assist rural communities

Co-developing land for both solar photovoltaic power and agriculture could provide 20% of total electricity generation in the United States with an investment of less than 1% of the annual US budget, new researchers found.

Home Solar Is Growing, but Big Installers Are Still Losing Money

The home solar business is growing fast as thousands of homeowners install panels on their roofs to save money. Yet the biggest companies that install and finance home solar systems are reporting hundreds of millions of dollars in losses. Those…
