Credit: Greg Stewart/SLAC National Accelerator Laboratory One of nature’s most important chemical reactions is now being captured in a breakthrough “molecular movie.” Using a unique combination of nanoscale imaging and chemical analysis, an international team of researchers has revealed a key step in the molecular mechanism behind the water splitting […]

New roll-to-roll production method could enable lightweight, flexible solar devices and a new generation of display screens. A new way of making large sheets of high-quality, atomically thin graphenecould lead to ultra-lightweight, flexible solar cells, and to new classes of light-emitting devices and other thin-film electronics. The new manufacturing process, which […]

Researchers developed a technique that uses a scanning tunneling microscope integrated with lasers and other optical components to trap appropriate molecules and measure the energy distribution of hot electrons in a thin gold film. Credit: Illustration by Enrique Sahagún Highly energetic, “hot” electrons have the potential to help solar panels […]

This graphical abstract summarizes how this work performs a comprehensive techno-economic analysis worldwide for photovoltaic systems using a combination of bifacial modules and single- and dual-axis trackers. The researchers found that single-axis trackers with bifacial modules achieve the lowest LCOE in the majority of locations (16% reduction on average). Yield […]

A schematic and electron microscope cross-section show the structure of an integrated, solar-powered catalyst to split water into hydrogen fuel and oxygen. The module developed at Rice University can be immersed into water directly to produce fuel when exposed to sunlight. Credit: Illustration by Jia Liang/Rice University ‘Artificial leaf’ concept […]

A focused laser is used to create thin films of tin dioxide. Credit: © 2020 Nakao et al. A clear semiconductor based on tin could improve solar power generation. Mobility is a key parameter for semiconductor performance and relates to how quickly and easily electrons can move inside a substance. […]

Highly porous programmable sponge for clean energy storage. Credit: Northwestern University Tremendous amounts of hydrogen and methane can be stored in nanoscopic pores. A research team led by Northwestern University has designed and synthesized new materials with ultrahigh porosity and surface area for the storage of hydrogen and methane for fuel cell-powered […]
