Stanford team develops coating to boost solar cell efficiency

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.

So what did you think of the dawn of the Turnbull Experiment 2.0? Is this going to be a new way forward for renewable energy in this country? A move away from the scorched earth policy of the Abbott administration? Or will it be a better-dressed, better-spoken continuation of the Abbott government’s war on renewables? [Read more…]

Solar + Flywheel Microgrid Saves 400,000 Litres of Diesel Annually

Solar has been installed with a huge flywheel to smooth its output in WA. The result is a town that is 60% solar powered, and a 400,000 litre reduction in annual diesel usage. Great Aussie innovation!

We’ve all seen the success of solar energy in our cities and regional towns. Australians are voting with their rooftops for clean, green solar power and the trend is increasing as solar reaches grid parity. But what of communities in our vast Outback? What of our small remote towns currently reliant on polluting fossil fuels such as diesel? It is here that microgrids, solar energy and the Outback are coming together to create a new, cleaner energy future.

In doing so, these microgrids for remote communities are giving the country a glimpse of a new way of accessing energy. [Read more…]

Will the Solar Council’s campaign in Canning help bring down a prime minister?

Will Abbott’s war on solar hurt his party’s prospects in Canning?

The heat is really on in Western Australia with the entry of solar energy in the Canning by election campaign. The seat which was recently vacated following the untimely death of then sitting member Don Randall, has become a focus for those looking for an indication of the electorate’s opinion on the government’s performance.

The previous incumbent was a popular representative and enjoyed a healthy margin in the opinion polls. However this has been whittled away in recent times due to the federal government’s incompetence, intransigence or bad luck, depending on your political point of view. [Read more…]

Solar energy in Texas rides into town

Yee-haw – the solar cowboys are comin’ to Texas!

Texas. Land of wide open spaces, cowboys, the Bush family, Tex-Mex food and barrels and barrels of oil. At least that’s the mental image I conjure up when I think of the state, mostly through memories of Dynasty ( the T.V show and the Republican presidents). Like all generalisations though, this is wildly inaccurate. Particularly the image of Texan energy. For there is a new power boom on the horizon as solar energy in Texas rides into town.

According to a recent Wall Street Journal report, companies such as First Solar, SunEdison and Recurrent Energy (a division of Canadian Solar) have staked their claims with a number of solar farms in the planning stage in and around famous oil fields in Texas. These will total around $US1 billion, according to State records. [Read more…]

Climate Institute poll finds Australians support renewables

wind turbines and solar

Renewables appear to be a vote winner. Someone may want to tell our government.

Banish any questions you may have had about whether or not Australians support renewables. If you listen to certain, unnamed cash-for-comment shock jocks, certainly in NSW anyway, you’d be of the opinion that Aussies generally find solar power and wind farms completely objectionable.

Of course nothing is further from the truth as a poll released by The Climate Institute last week to coincide with the unveiling (dare we say unravelling?) of the government’s emissions reduction target. The poll shows the extent to which Aussies prefer solar and wind energy over that of fossil fuel. [Read more…]

NZ switches off coal in favour of renewable energy

No more coal fired power stations in NZ

News that our neighbour across the ditch is switching off fossil fuels in favour of renewables will have sent a shudder through the corridors of power this week. For New Zealand has announced that it will close its last two coal mines by 2018 and aim towards a 90 percent renewable energy target by 2025.

The New Zealand decision to support renewables has been forced on the Shaky Isles due to the increasing cost competitiveness of renewables such as solar, wind, hydro and geo-thermal and an growing lack of demand for fossil fuel-based energy. [Read more…]

Facebook, solar energy and drones join to connect billions to the Internet

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…]

China puts faith in large-scale concentrating solar power as world watches

A solar tower – similar to one of the 6 to be built in the Gobi desert

China was in the renewable energy news again this week though this time it wasn’t about the latest in solar panel technology or trade disputes. For the big (read huge) story was Chinese regional media reporting the start of construction of the country’s first large-scale concentrating solar power (CSP) plant.

To be carved out of 2550 hectares of the Gobi desert, the plant will use two 135 MW solar thermal plants in its first phase, with enough thermal energy storage to power half a million (!) homes in Qinghai Province.  [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…]
