Smaller scale solutions needed for rapid progress towards emissions targets

Low-carbon technologies that are smaller scale, more affordable, and can be mass deployed are more likely to enable a faster transition to net-zero emissions, according to a new study. Innovations ranging from solar panels to electric bikes also have lower investment risks, greater potential for improvement in both cost and performance, and more scope for…

Uncertain climate future could disrupt energy systems

Scientists have published a new study proposing an optimization methodology for designing climate-resilient energy systems and to help ensure that communities will be able to meet future energy needs given weather and climate variability.

Shedding light on optimal materials for harvesting sunlight underwater

There may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles, report researchers. New research develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band gap semiconductors, rather than the narrow-band semiconductors used in traditional silicon…

Simple, solar-powered water desalination

A completely passive solar-powered desalination system could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source. Read Full Article Here For more great articles: Solar Energy News — ScienceDaily

Lasers etch a ‘perfect’ solar energy absorber

Researchers demonstrate how laser etching of metallic surfaces creates the ”perfect solar energy absorber.” This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrate solar energy harnessing with a thermal electric generator. Read Full Article Here For more great articles: Solar Energy News — ScienceDaily

Anti-solar cells: A photovoltaic cell that works at night

What if solar cells worked at night? That’s no joke. In fact, a specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime, according to a recent concept article.

Solar power from ‘the dark side’ unlocked by a new formula

Most of today’s solar panels capture sunlight and convert it to electricity only from the side facing the sky. If the dark underside of a solar panel could also convert sunlight reflected off the ground, even more electricity might be generated.
