New silicon solar cells, created in Australia, have reached 25% efficiency - a new world record for the technology.The world-leading silicon cell is now six per cent more efficient than the next-best technology, according to Professor Green, Executive Research Director of the ARC Photovoltaic Centre of Excellence.
The boost in efficiency is due to the technology's redefinition of the available light spectrum allowing it to capture more energy at its extremes.
The new technology inches closer to the theoretical limit of 29% efficiency for this generation of solar cells.
Commercial production is already in negotiations and could soon make low cost, high output solar energy an even better way for individuals and businesses to reduce their environmental impact.

Isn't CSP much more efficient that that?

I think it is, but it's not something you can put on the roof of your house, or in a building.

Human ingenuity, focus your attention on the problem at hand and the solution presents its self.
Next step would be to make it an affordable...solution! - 1 year ago

I've been hearing a lot of news about the development of solar cells lately. I'm pretty sure this will be the main source of energy in the future.

Add this to LED and CFL lighting, light pipes, and good insulation, you get some real conservation.
Then we need to start looking at non-AC computers and appliances. A friend of mine is experimenting with adding low-voltage wiring to his home for exactly this purpose. We only needed AC to make it easier to transmit the voltage down long power lines, if we have our own panels then we can bypass the power conversion and use DC directly and efficiently.

Really?
Never knew that about DC. Is it significantly more inefficient? What would that kind of rewiring stand to save? - 1 year ago

Grinhooks:
DC, direct current, is what nearly all electronic devices actually run on. AC, alternating current, is used to get the power from the generators down the lines to the homes, then every device has a section called a power supply in it to convert the AC into the DC it really needs. Of course that conversion process is inefficient, wastes a lot of power. If we used DC directly, we'd use a lot less power, AND our devices would cost less because of all the extra hardware we wouldn't need.

Slowly but surely we will become free of fossil fuels and the Arabs and the Bush's and big oil can go to hell for all I and I am sure many other people care!!!!!!!!!!!!!!!!!!

I guess a lot of people forget the other side of the equation that there are a lot of batteries that have been developed to store the solar power

Good, now we can try to advance this technology to and eve greater level. Who know the next step could be 35%.

The innovations are awesome, it's the implementation that really needs to be worked on!
When are we actually gonna start taking the switch seriously? Do we really have to wait for another President before we get started on this?

Efficient as in 100% in, 100% out, as well as having it stored for a few years without change in how much is there, right? Too bad we're not that efficient.

why waste money on developing something that wont even be able to achieve 30% efficiency?
why not invest in something that will take advantage of the whole spectrum of light? - 1 year ago
