No Joke — Algeria Plans 4 Gigawatt, 5 Year Solar Power Initiative

Posted by in categories: solar power, sustainability

Make no small plans. That seems to be the logic among the leaders of Algeria.

For some perspective, I just wrote about the corporate behemoth Amazon, which hopes to get to 100% renewable electricity by 2025 (firm target of 2030) and has a whopping total of 31 utility-scale wind and solar power plants built or planned that add up to 2,900 MW of total power capacity. That’s 2.3 gigawatts (GW). Algeria is talking about building 4 gigawatts of solar power capacity in 5 years. That’s a pretty stunning target.

Solar panel recycling: Turning ticking time bombs into opportunities

Posted by in categories: solar power, sustainability

Australia has certainly demonstrated its appetite for solar power. Now, with the average lifespan of a solar panel being approximately 20 years, many installations from the early 2000’s are set to reach end-of-life. Will they end up in landfill or be recycled? The cost of recycling is higher than landfill, and the value of recovered materials is smaller than the original, so there’s limited interest in recycling. But given the presence of heavy metals, such as lead and tin, if waste is managed poorly, we’re on track for another recycling crisis. A potential time bomb could present itself as an opportunity, however, if the global EV industry showed an interest in the recovered solar products.

Italians Can Now Install Rooftop Solar PV Systems For Free

Posted by in categories: biotech/medical, government, policy, solar power

The Italian government had one of the early invasive experiences of the covid-19 pandemic. Scientists in Italy responded to the global crisis with serious research into the concern. Perhaps results of these inquiries and related information have affected policy makers. Italian homeowners now have new opportunities to put clean energy on the top of their roofs.

A New Bionic Eye Could Give Robots and the Blind 20/20 Vision

Posted by in categories: cyborgs, nanotechnology, robotics/AI, solar power, sustainability, transhumanism

Good news.


In a paper published last week in Nature, though, researchers from Hong Kong University of Science and Technology devised a way to build photosensors directly into a hemispherical artificial retina. This enabled them to create a device that can mimic the wide field of view, responsiveness, and resolution of the human eye.

“The structural mimicry of Gu and colleagues’ artificial eye is certainly impressive, but what makes it truly stand out from previously reported devices is that many of its sensory capabilities compare favorably with those of its natural counterpart,” writes Hongrui Jiang, an engineer at the University of Wisconsin Madison, in a perspective in Nature.

Solar Technology Breakthrough: World Record Quantum Dot Solar Cell Efficiency

Posted by in categories: nanotechnology, quantum physics, solar power, sustainability

The development of next-generation solar power technology that has potential to be used as a flexible ‘skin’ over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland.

UQ researchers set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called ‘quantum dots’, which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device.

Next-generation perovskite solar cells pass strict international tests

Posted by in categories: solar power, sustainability

Australian scientists have for the first time produced a new generation of experimental solar energy cells that pass strict International Electrotechnical Commission testing standards for heat and humidity.

The research findings, an important step towards commercial viability of perovskite solar , are published today in the journal Science.

Solar systems are now widespread in both industry and domestic housing. Most current systems rely on silicon to convert sunlight into useful energy.

Efficient, ‘green’ quantum-dot solar cells exploit defects

Posted by in categories: quantum physics, solar power, sustainability

Novel quantum dot solar cells developed at Los Alamos National Laboratory match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements that most solar cells of this type rely on.

“This quantum-dot approach shows great promise for a new type of toxic-element-free, inexpensive that exhibit remarkable defect tolerance,” said Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured on the cover of the journal Nature Energy.

Not only did the researchers demonstrate highly efficient devices, they also revealed the mechanism underlying their remarkable defect tolerance. Instead of impeding photovoltaic performance, the defect states in copper indium selenide quantum dots actually assist the photoconversion process.
