Squeezing a rock-star material could make it stable enough for solar cells
www.solarenergyconnect.com

Stanford CA (SPX) Jan 25, 2021 Among the materials known as perovskites, one of the most exciting is a material that can convert sunlight to electricity as efficiently as today’s commercial silicon solar cells and has the potential for being much cheaper and easier to manufacture. There’s just one problem: Of the four possible atomic […]

New green materials could power smart devices using ambient light
www.solarenergyconnect.com

London, UK (SPX) Nov 16, 2020 We are increasingly using more smart devices like smartphones, smart speakers, and wearable health and wellness sensors in our homes, offices, and public buildings. However, the batteries they use can deplete quickly and contain toxic and rare environmentally damaging chemicals, so researchers are looking for better ways to power […]

Solar Power Stations in Space Could Be the Answer To Our Energy Needs
www.solarenergyconnect.com

Amanda Jane Hughes, Lecturer, Department of Mechanical, Materials and Aerospace Engineering at University of Liverpool Stefania, and Soldini Lecturer in Aerospace Engineering at University of Liverpool, write: A space-based solar power station could orbit to face the Sun 24 hours a day. The Earth’s atmosphere also absorbs and reflects some of the Sun’s light, so […]

A Group of Materials Called Perovskites Could Be a Game-Changer For Solar Power
www.solarenergyconnect.com

Researchers from Australia have discovered that the widely acclaimed mineral perovskite can be used to transform the solar industry through cheaper and more efficient photovoltaics. The Independent reports: Perovskite, which is forged deep within the Earth’s mantle, has been hailed for its unprecedented potential to convert sunlight into electricity. Researchers have already improved its sunlight-to-energy […]

'Green Hydrogen' From Renewables Could Become the Cheapest 'Transformative Fuel'
www.solarenergyconnect.com

The Guardian reports: “Green hydrogen” made with wind and solar electricity could become the cheapest form of what the Australian government has described as a “transformative fuel” much faster than expected, analysts believe. Chinese manufacturers have reported making systems to create hydrogen with renewable energy for up to 80% less than official Australian estimates from […]

Physicists Argue That Black Holes From the Big Bang Could Be the Dark Matter
www.solarenergyconnect.com

Long-time Slashdot reader fahrbot-bot quotes Quanta magazine: It was an old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter. It fell out of favor for decades, but a new series of studies has shown how the theory can work… Their very blackness makes it hard to estimate how many […]

Could Spacecraft of the Future Be Powered By 'Lattice Confinement' Nuclear Fusion?
www.solarenergyconnect.com

schwit1 writes: Researchers at NASA’s Glenn Research Center have now demonstrated a method of inducing nuclear fusion without building a massive stellarator or tokamak. In fact, all they needed was a bit of metal, some hydrogen, and an electron accelerator. The team believes that their method, called lattice confinement fusion, could be a potential new […]
