A low-cost method for solar-thermal conversion that's simpler and greener

Researchers have developed a simple, low-cost, and environmentally sound method for fabricating a highly-efficient selective solar absorber (SSA) to convert sunlight into heat for energy-related applications. The team used a 'dip and dry' approach whereby strips coated with a reactive metal are dipped into a solution containing ions of a less reactive metal to create plasmonic-nanoparticle-coated foils that perform as well or better than existing SSAs, regardless of the sun's angle.

How 139 countries could be powered by 100 percent wind, water, and solar energy by 2050

The latest roadmap to a 100 percent renewable energy future outlines infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; and a net increase of over 24 million long-term jobs.

Cyborg bacteria outperform plants when turning sunlight into useful compounds

Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.

Solar panels: Nanotechnology gives green energy a green color

Solar panels have tremendous potential to provide affordable renewable energy, but many people see traditional black and blue panels as eyesores. Architects, homeowners and city planners may be more open to the technology if they could install colorful, efficient solar panels, and a new study brings us one step closer. Researchers have developed a method for imprinting existing solar panels with silicon nanopatterns that scatter green light back toward an observer.

Turning homes into power stations could cut household fuel bills by more than 60 percent

Energy bills could be cut by more than 60 percent -- saving the average household over £600 a year -- if homes were designed to generate, store and release their own solar energy, a report has revealed. The concept has already been proven and is operating successfully on a building in the UK.

Solar glasses generate solar power

Organic solar cells are flexible, transparent, and light-weight -- and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon solar cells. Researchers now present sunglasses with colored, semitransparent solar cells applied onto lenses that supply a microprocessor and two displays with electric power.
