This is New: Solar Panel Plan Industry

Renewable energy is important. The one is Solar energy which stored by solar panel. But, in 20th century until now, there are no inovation. So what's the matter. Check it out...

Solar panel installations have become increasingly popular, but the solar panel manufacturing industry is in the doldrums because supply far exceeds demand. The poor market may be slowing innovation, but advances continue; judging by the mood this week at the IEEE Photovoltaics Specialists Conference in Tampa, Fla.,
people in the industry remain optimistic about its long-term prospects.
The technology that's surprised almost everyone is conventional crystalline silicon. A few years ago, silicon solar panels cost $4 per watt, and Martin Green, professor at the University of New South Wales and one of the leading silicon solar panel researchers, declared that they'd never go below $1 a watt. "Now it's down to something like $0.50 of watt, and there's talk of hitting 36 cents per watt," he says.

Industrial

The U.S. Department of Energy has set a goal of reaching less than $1 a watt — not just for the solar panels, but for complete, installed systems — by 2020. Green thinks the solar industry will hit that target even sooner than that. If so, that would bring the direct cost of solar power to $0.06 per kilowatt-hour, which is cheaper than the average cost expected for power from new natural gas power plants. (The total cost of solar power, which includes the cost to utilities to compensate for its intermittency, would be higher, though precisely how much higher will depend on how much solar power is on the grid, and other factors.)
All parts of the silicon solar panel industry have been looking for ways to cut costs and improve the power output of solar panels, and that's led to steady cost reductions. Green points to something as mundane as the pastes used to screen print some of the features on solar panels. Green's lab built a solar cell in the 1990s that set a record efficiency for silicon solar cells — a record that stands to this day. To achieve that level of efficiency, he had to use expensive lithography techniques to make fine wires for collecting current from the solar cell. But gradual improvements have made it possible to use screen printing to produce ever finer lines. Recent research suggests that screen printing techniques can produce lines as thin as 30 micrometers — about the width of the lines Green used for his record solar cells, but at costs far lower than his lithography techniques.

Inovation is a Must

Green says this and other techniques will make it cheap and practical to replicate the designs of his record solar cell on production lines. Some companies have developed manufacturing techniques for the front metal contacts. Implementing the design of the back electrical contacts is harder, but he expects companies to roll that out next.

Meanwhile, researchers at the National Renewable Energy Laboratory have made flexible solar cells on a new type of glass from Corning called Willow Glass, which is thin and can be rolled up. The type of solar cell they made is the only current challenger to silicon in terms of large-scale production—thin-film cadmium telluride. Right now such solar cells are made in batches (as are silicon solar cells), but the ability to make them on a flexible sheet of glass raises the possibility of continuous roll-to-roll manufacturing (like printing newspapers), which can reduce the cost per watt by increasing production.

Conclution 

Personally, the renewable energy is important. So we must take care of it. Don't just focus with mobile or gadget. But focus on energy, specially renewable energy. So, what's next future is our hand.
Perfect.
