Recent extreme weather events have underscored the need to reduce CO₂ emissions that increase global temperatures. This requires a rapid transition from an energy economy to renewable energy sources, the cheapest of which is solar photovoltaic (PV). And our recently published research shows how we can lower shift costs even further using a cheaper form of silicon for highly efficient solar panels. Australia has taken the lead with solar PV installations, but our solar energy journey has only just begun. This year, humanity reached the milestone of 1 terawatt (TW) – 1 million × 1 million watts – installed solar capacity. However, experts predict 70TW of solar PV may be needed by 2050 to power all sectors of the economy. To help drive this rapid uptake of solar PV, we need solar panels with high efficiency and low cost. Over the past ten years, several new solar cell designs have resulted in record high efficiency. The problem is that this design also requires higher quality materi

Ricky Barone installed a solar system on his roof in 2014 to make the most of North Queensland’s sunshine and save money on his electricity bill. Key points: Ricky Barone has been told the installation is a fire hazard but the retailer will not uninstall it A number of regulatory agencies receive complaints about diesel retailers, manufacturers and installers Some of the main issues raised were related to price, quality and high-pressure sales Since its installation, however, it has cost thousands of dollars and years without sleep. It was only this year that a so-called solar doctor inspected his roof panels did Mackay’s man realize the potential danger he was in. “He [the solar inspector] basically saying it was badly installed and there was a high chance it could catch fire,” Barone said. “I’m very disturbed and I haven’t slept well thinking about it.” Mr Barone said it was a two year wait to get the solar system installed by a local company, so he instead turned to a company based

The worlds of the solar system beyond Earth have amazing surface features. Thanks to planetary science missions, we see images of canyons, craters and cliffs around the world. One day, these places will provide new challenges for mountaineers and climbers. In particular, Mars will be a favorite destination. Future climbers and mountaineers will be spoiled for choice, even if they have to put on a spacesuit to get their thrills. For example, there is the canyon region of Valles Marineris. It is the largest known feature in the solar system, many times larger than Earth’s Grand Canyon. The European Space Agency’s Mars Express orbiter has just returned a stunning image of this gorge. Pictures of Mars and Mars Express The final view from the Mars Express focuses on two trenches—the so-called “chasma”—in western Valles Marineris. They are Ius Chasma and Tithonium Chasma, the deepest part of the canyon. The whole system looks complex and complicated. That’s because it was formed fro

This is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is abundant on the surface of Mars, giving it its reddish color and its nickname "Red Planet." The name Mars comes from the Roman god of war. ” data-gt-translate-attributes=”[{” attribute=””>Mars Express’s latest image release takes us over two ruptures in the martian crust that form part of the mighty Valles Marineris canyon system. Valles Marineris cuts across Mars similar to how the Grand Canyon cuts across the United States, except the latter is tiny in comparison. At

The moon could be a huge rocket swap and a stopping point for humans to travel to other parts of the solar system in 2069 – the 100th anniversary of the first moon landing. This month marks 53 years since humanity made the giant leap and NASA’s Apollo 11 mission placed US astronauts Neil Armstrong and Buzz Aldrin on the surface of the brightest satellite on Earth. Now space scientists around the world are considering how the moon could become a “changeable” launch pad for the next half century.

Currently, scientists are trying to calculate whether it is possible to put a space station into orbit around the moon, with a view to sending people to Mars or even further into space. “I think that will be the future. Our next step from Earth is to figure out how we can use t

When it comes to searching for asteroids, we have a blind spot. It may seem counterintuitive, but the asteroid’s most important discoveries are now being made at dusk, when astronomers can see up close to the horizon – and close to the sun – for what little is known. asteroids orbiting within the orbits of Earth, Venus and even Mercury. In perspective published in Science today, asteroid hunter Scott Sheppard of the Carnegie Institution of Science highlights the new “twilight telescope” surveys and the riches they are beginning to discover. It includes the first asteroid with an interior orbit to Venus and the one with the shortest known orbital period around the sun, both of which have been unearthed in the past two years. It also includes “city killers”, asteroids large enough that if they hit Earth the damage will be severe. “We’re doing a full survey looking for anything moving around the orbit of Venus, which is somewhere we haven’t surveyed very deeply in the past with anyth

Octopus Investment Australia has officially launched a $10 billion renewable energy “platform,” which will seek to finance large solar, wind and battery storage projects and has purchased Australia’s largest operating solar farm. Octopus Australia – a subsidiary of one of the world’s largest investors in clean energy, the Octopus Group – said on Wednesday it had simultaneously closed two full subscription funds co-invested in Australia’s multibillion-dollar renewable energy portfolio. The two investment vehicles are the Octopus Australia Sustainable Investments (Oasis) Fund, open to institutional investors, and the Octopus Renewable Energy Opportunities (Oreo) Fund, open to wholesale investors. Among the institutional investors who have joined the Oasis fund so far are the federal government’s Clean Energy Finance Corporation and Australian pension fund Hostplus, which has more than 1.5 million members and $86.6 billion in funds under management. Octopus said the secured portfolio c

Credit: ESA Astronomers have proposed a concept mission to fly a neutrino observatory into orbit around the sun to get a better picture of what’s going on in the sun’s core. Astronomers have very few tools to peer into the heart of the sun. Fortunately, the constant nuclear reactions taking place in the sun’s core as hydrogen combine to form helium release a relentless flood of neutrinos. Neutrinos are tiny, ghost-like particles that almost never interact with matter. On Earth we’ve built giant detectors to catch the occasional neutrino. Astronomers have used these neutrinos to understand the nuclear processes taking place inside the sun and to probe the edges of known physics. But our observatories on Earth are basically limited because our planet is so far from the sun. So what if we took the neutrino observatory into space? A te

Australia has some impressive solar PV credentials, including the use of world-leading technology by households and businesses and world-renowned and ongoing contributions to research and development. But can we make the stuff? It’s a question that comes up frequently, these days, when the newly elected Labor government talks about reviving Australian manufacturing, as fossil fuel costs send grid prices soaring, and when war at the height of the pandemic disrupts supply chains as does the shift to energy. renewable. need to shift some gears. In announcing the Alba government’s $45 million extension of funding for the Australian Center for Advanced Photovoltaics last month, federal energy minister Chris Bowen measured the solar challenge. “Solar panels all over the world, the technology that is in them, is not a little to be found here [at the University of New South Wales] and at other Australian universities. That’s something we can be proud of. But we have to take it now to t
