In a development that will bring a smile to the faces of Harry Potter fans, researchers at the Karlsruhe Institute of Technology (KIT) announced this week the success of using invisibility cloaks to improve solar cell efficiency.

While the technology sounds very J. K. Rowling, the benefits of invisibility cloaks for solar cell efficiency — or at least technology that acts very much like invisibility cloaks — are very real. [Read more…]

Stanford team develops coating to boost solar cell efficiency

September 29, 2015 2017-10-25T09:31:35 by 1 Comment
mono and poly crystalline solar cells

When solar cells get hot they lose efficiency. Researchers have developed a coating that keeps cells cooler.

Contrary to popular thought, heat reduces solar cell efficiency. As the cells heat up from the direct glare of the sun, their efficiency in converting light into electricity drops markedly. Depending on the system used and the location, losses can reduce output up to 10 to 25 percent.

This conundrum has vexed the industry for many years. After all, solar cells need the sun to work and this generates heat. So how to solve this problem and increase the light-to-electricity efficiency of solar cells?

Enter a team of researchers from Stanford University who have developed a transparent coating for the cells. The film keeps the cells cool as they heat up under the sun. Made of patterned silicon, the secret to this remarkable film is that, while it allows visible light to pass, it also absorbs and even emits the infrared rays, the source of thermal radiation.

What do Facebook, solar energy and drones have in common? Not a great deal you may think; after all drones have a sinister reputation in our day and age. For they are usually thought of as accessories to destroy, maim or kill, the latest in warrior technology designed to conquer and “take out” perceived or real enemies.

Indeed it’s difficult to think of a drone being used for a positive purpose such as to help people connect, interact and research. However Facebook is out to prove us wrong on this point with its Aquila drone and it is solar energy that will power this drone connectivity revolution. [Read more…]

How much will eliminating silver in solar cells drive costs down?

July 22, 2015 2017-10-25T09:34:16 by 2 Comments
silver bars and solar panels

Solar panel manufacturing uses about 2.8 million ounces of silver for every GW of solar panels manufactured. New technology hopes to reduce this to zero.

Ever considered how much the amount of silver in solar cells adds to their cost? What if silver were eliminated completely from the production of solar panels?

The price of solar cells has already reduced considerably in recent years due to improved production efficiencies, making solar cells affordable for many. However the elimination of the high cost silver from the production would realise a long term dream of producers and make solar energy even more cheaper than it has already become. [Read more…]

You get the best renewable energy stories tucked away in the rural press. Proof that solar power innovation in the bush is moving ahead by leaps and bounds. This despite the often backwards policy of our elected representatives.

So it was this week when a bit of digging unearthed the unveiling of a $3.6 million solar power facility in Newbridge in Central Victoria. The plant, developed by renewable research and development company RayGen Resources, combines PV cells with concentrating solar technology. [Read more…]

Researchers use photosynthesis to directly create liquid fuel from solar

February 18, 2015 2017-10-25T09:39:36 by 1 Comment
leaf and solar panel

Harvard scientists are mimicking photosynthesis by converting solar electricity directly into a liquid fuel.

Solar power using photosynthesis is the most ancient — and successful — form of energy production. Plants have used this method for over a billion years, harvesting sunlight, combining it with water and turning this abundant solar energy into food. Now researchers at Harvard University are looking to use the process in a really novel way. [Read more…]

Solar cars are quickly maturing from wacky racers like this to mass market models. Bring it on!

Ever considered the seemingly endless possibilities of solar thin film technology for mobile energy generation? Mr Li Hejun, CEO of China-based thin film solar company Hanergy Thin Film Power Group Ltd certainly does and outlined his vision (or dream depending on your point of view), of a future where this technology dominated mobile energy needs.

Mr Li presented his strategy for mobile energy future as “…a revolution in the way energy is generated and used” in a keynote speech delivered at a ceremony in China last week to launch its global thin film solar product innovation competition. [Read more…]

Perovskite: the Bond villain at the head of the new solar cell revolution

blofeld and soolar panel

Ernst Stavro Blofeld, a pussy and some solar panels, yesterday.

One of the great enjoyments in writing this blog is the opportunity it gives me to bring you news about the latest innovation in solar energy. From breakthroughs in solar cell technology to improvements in solar lifestyle, to the latest progress in solar farms, advancements in the research labs, universities and science organisations never seem to end.

However this week sees not a new discovery but the return of an old SolarQuotes favourite: perovskite. More specifically the role it will play in the future of photovoltaics and solar energy generation.

Favourite? Well yes, for two reasons. We’ve written before on the potential game changing aspects of perovskite in solar cell technology and — just as importantly — because the mineral sounds so much like it escaped from a James Bond film. [Read more…]

ARENA: the government renewable energy agency that refuses to go away

ARENA - the gift that keeps on giving.

ARENA – the gift that keeps on giving.

Remember ARENA? The plucky Australian Renewable Energy Agency that has helped many renewable energy ventures and research with seed funding and other support? The ongoing benefits of ARENA include not only financial support but also because their involvement has helped pave the way for research and development in partnership with the private sector.

Wait. Ongoing? Didn’t ARENA get axed by the feds in their anti-renewables Budget cuts zeal a while back?

Well no. At least not yet. For ARENA, to quote an oft-used phrase, is the gift that keeps on giving.

Though the agency has, as you’ve probably heard, been axed by the federal government as part of its thinly-disguised ideological campaign against renewables, it still refuses to roll over and die. [Read more…]

Selling Solar By Making It Look Good!

November 3, 2014 2018-05-09T11:05:49 by 2 Comments

Last week, CSEM debuted the world’s first white solar modules with the promise of solar panels in any colour you wish. This new product has great potential to increase the deployment of solar. Why is that? Because it’ll look good.

While it may sound petty, many have been hesitant to switch to solar power because the modules stick out like a sore thumb on buildings. Now that CSEM has developed solar panels that will blend into a building’s structure with no visible cells or connections, architects can install solar panels into their design without having to compromise the aesthetic of their project.

Check out their video here (and marvel at how many coffees the voiceover guy must have had – gee he sounds excited!):
