A machine-learning algorithm has been developed by scientists in Japan to breathe new life into old molecules. Called BoundLess Objective-free eXploration, or Blox, it allows researchers to search chemical databases for molecules with the right properties to see them repurposed. The team demonstrated the power of their technique by finding molecules that could work in solar cells from a database designed for drug discovery.

Chemical repurposing involves taking a molecule or material and finding an entirely new use for it. Suitable molecules for chemical repurposing tend to stand apart from the larger group when considering one property against another. These materials are said to be out-of-trend and can display previously undiscovered yet exceptional characteristics.

‘In public databases there are a lot of molecules, but each molecule’s properties are mostly unknown. These molecules have been synthesised for a particular purpose, for example drug development, so unrelated properties were not measured,’ explains Koji Tsuda of the Riken Centre for Advanced Intelligence and who led the development of Blox. ‘There are a lot of hidden treasures in databases.’

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.

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.

Solar Energy Corporation of India (SECI) has awarded a large tender for steady supply of renewable energy. Part of the project awarded under this tender will supply power to a high-profile area in India’s capital city.

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.

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.

Transparent solar panels are regarded as the “wave of the future” for new solar technologies. Ubiquitous Energy and Physee are 2 pioneers.

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.

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 cells, are published today in the journal Science.

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