Solar Efficiency Record Broken

When it comes to eeking another fraction of a percentage point of power out of discount viagra perscription drug a solar panel, we're pretty good at not paying attention. I mean, what's the difference between 40.7% and 40.8% anyway?

Generally these efficiency gains aren't all that important to the cialis canada generic future of the solar economy. Yes, it's a new world record, but the photovoltaic modules that are most economical are only like 20% efficient. They're better because they're cheaper...and these record-breaking panels are NEVER cheap.

But this one is worth talking about.

Scientists at the National Renewable Energy Laboratory in Colorado eeked that extra fraction of a percent out using a few very interesting techniques. Highly efficient solar cells have to split light into segments and tramadol cod cash on delivery then capture each hunk of wavelengths separately. This lets the panel be efficient across a wide spectrum.

This new chip uses an entirely different system to split the wavelengths (gallium indium arsenide and gallium indium phosphide...if you're curious.) The result is a much thinner and lighter solar cell that could even possibly be flexible.

The chips is also optimally efficient under concentrated sunlight. Concentrated sunlight is preferable because large areas of light can be concentrated on buy tramadol online small areas of photovoltaic material. And since the PV material (especially this ultra-efficient stuff) is extremely expensive, using less per unit of sunlight captured is way better.

In short, this isn't just another tiny bump in efficiency, it's an entirely new solar cell, and one that could be very useful not just for satellites, but also for utility scale solar. Though, to be fair, the path to the commercial market is good choice cialis prescriptionsgeneric cialis sale always pretty arduous for these new solar technologies.

Hmm, not much gain

So, basically, not much gain, developments, but nothing exciting.

Actually, could very very exciting

Although little gain in efficiency. The fact there is a whole different approach is a very cool development. This allow for many more options for high-efficiency solar cells to come to 25mg viagra market.
DARPA Already Did IT

It's called PRISM, and they separated light to more sensitive PV cells.
If DARPA already did it ...

...then where the hell is it? One of the best inventions that we -really- need, which you say DARPA has "done", and it's nowhere to be seen.

Dude that is absolutely amazing! Once again you ahve hit the nail on the head!

Good to see continued development in sol

Sometimes a technology can be advanced long-term by a lateral movement. It might be easier to make even more gains against a newer design. I'm hoping you guys pickup more efficiency and make going solar truly cost-effective.

Wake me up when I can buy solar at home depot for less than $500 and it will power my house.

why isn't PV sold at Home Depot anyway? anyway here's an open source project that's kind of fun:
