Today the Solar Racing Team of the University of Adelaide gave Finn and I the opportunity to take Lumen, their solar racer, for a spin. And I was there to take Finn’s picture as he nailed it and completely managed not to hit or destroy anything at all. Well done, Finn!
Finn, about to take the University of Adelaide’s Solar Racing Team’s vehicle for a spin.
An unassuming lump of perovskite. “The fastest improving solar cell technology there has ever been.”
Weâve previously covered the novelty of perovskites as a potential game changer for solar cell cost and efficiency, and also asked why, with such a name, they havenât as yet debuted in the latest James Bond blockbuster. But perovskite solar cells in commercial production as the âNext Big Thingâ in solar cell technology? Surely thatâs a long, long way off? [Read more…]
The performance of solar cells is often determined by the range of weather conditions. However a breakthrough by Chinese scientists has brought closer the practicality of solar cells being able to generate energy during… wait for it… both sunny and rainy days. [Read more…]
Another breakthrough on the road to cheap, efficient perovskite solar cells
A combined Australian and Chinese team has developed a water-resistant perovskite solar cell using a specially-designed dipping technique. The new technology will dramatically boost the humidity tolerance of the cells, the lack of which was previously considered a stumbling block to commercialisation. [Read more…]

High altitude solar balloons deployed where clouds wonât interfere with their output may be the stuff of science fiction. But are they? At least one reputable research house thinks this is where solar panels should be, saving space used for solar farms for much needed agricultural land. All while more than doubling solar conversion efficiency. [Read more…]

The advantages of solar energy in rural communities is well documented. Particularly those who are located in more remote parts of the land and countries where access to the grid is difficult, if not impossible.
For isolated communities in developing countries face enormous problems, both financial and logistical, to access centralised energy. To remedy this, aid organisations now supply people with solar panels for energy, lighting and heating. However this week saw news of a partnership between solar inverter leader SMA and practical aid group Farm from a Box that promises to take solar energy and micro-farming to a new level. [Read more…]
Is this what solar panel warehouses will look like in the future?
Completely transparent windows that generate solar power have been a goal for researchers for many decades. Previous attempts at transparent solar cell technology have achieved only partial success with the windows left with a decided tinted effect and the resulting office/room space.
This is not the ideal working conditions for offices, unless of course you work in a discotheque!
However now a team of researchers at Michigan State University have resolved that problem by unveiling their unique transparent solar cell technology, which creates energy from the sun when placed over a window or glass surface. [Read more…]

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 â or at least technology that acts very much like invisibility cloaks â are very real. [Read more…]
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.

Solar Power – delivering the internet to millions. Image: Facebook
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 âtake outâ perceived or real enemies.
Indeed itâs 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…]
