A new record for concentrated photovoltaics efficiency has been broken by Solar Junction, the same company that announced a 41.4% efficiency in February. The new score is 43.5% and their multi-junction solar cells can be produced right away.
One by one, states across the globe become conscious of their solar energy potential and act accordingly ÃƒÂ¢€Ã¢â‚¬Å“ those that can, of course. Australia is one of them. With a growing demand for electricity and the challenge of polluting less, they try to move the weight from a coal-based industry to one that uses mostly solar power.
The great side about physics is that it discovers things where you would least expect them to be found. For example, just when you thought you knew everything about light, here comes an exciting new discovery that could become an alternative source of power, involving the magnetic properties of light!
Solar energy as we know it today has a great potential, but could need some help with the efficiency part. Apparently, solar cells are not very economical: almost one third of the light is reflected from the surface and the panel’s materials only reabsorb some of the energy.
Google has recently announced the construction of a new solar power plant in the Mojave Desert, California. BrightSource Energy is the local developing company in charge of the project and the power plant itself is known under the name of Ivanpah Solar Electric Generating System (ISEGS).
Even if this is the country’s third solar-powered car, it is called “Iranian Gazelle 2″ and it is a completely national product both in its conception and construction. Presented on Sunday, the car’s project manager, Karen Abarnia assures us that it excels on a number of features, as sequels usually do.
If one goes down, they all go down: I’m talking about solar panels and the way they work ÃƒÂ¢€Ã¢â‚¬Å“ or don’t anymore – when lined up. There are various reasons they could stop functioning: an apparently harmless thing as a cloud shading just one of them is enough to affect the performance of the rest. Yes, they are that sensitive!
Pakistan is catching up on its enormous solar energy potential pretty soon: in less than a year, the Pakistan Engineering Council (PEC) will build the country’s first on-grid solar electricity system. It will be put in place because of the energy crisis and will be a big stimulus for the local economy.
General Electric (GE), the American conglomerate that has reinvented itself as a green energy giant, has two pieces of news for us: 1) it wants to build a thin-film solar factory in the U.S. and 2) it has bought the PrimeStar Solar Company.
Now here’s something truly optimistic for our blog’s visitors: a solar powered car-wash has recently opened in the US city of Stamford, Connecticut. Its owner, Mr. Gregg Mercede admits that he wanted to invest his money in something durable and eco-friendly, while still ensuring a great quality of his services.
One day we will get as far as taking a shower and turning on the heat in our room with the energy our roof has collected over the day. And when I say this I feel encouraged by the new solar-thermal device based on polymer material that Wake Forest University researchers invented.
Indian company Tata is getting more and more involved in the renewable energy sector. After the agreement their CEO had with Daniel Nocera for producing energy from water, they now make a deal with Australia-based Sunengy, which manufactures LSAs (Liquid Solar Arrays), basically floating concentrated solar power systems (CSP).
A team of Georgia Tech students (Solar Jackets) has converted an Audi TT into a “solar-assisted electric vehicle,” in order to participate …
Honestly, the reflection off my phone’s screen annoys me, and I think it does the same to anyone. Some French scientists from a company named Wysips have produced a 100-micron thin film that uses the ambient light to charge the phone’s battery – in a very cheap manner.
MIT professor Daniel Nocera, the inventor of a type of electrolysis that mimics the plants photosynthesis, and Ratan Tata, the CEO of the Indian Tata group, have signed a funding agreement allowing the Tata group to commercialize Nocera’s invention which produces power from water.
