solar cell manufacturing costs cut by an estimated 50 percent
"On Friday, Secretary of Energy Stephen Chu announced a "game changing" development in solar energy. A company called 1366 Technologies
, headquartered in Lexington, Mass., has developed a silicon solar wafer that would cut the cost of solar cell manufacturing by an estimated 50 percent
Unlike traditional wafers--which are sliced from a large block, resulting in considerable losses of material (up to 50 percent)--these new wafers are individually cast to specific measurements, a more efficient model of production.
In 2009, ARPA-E made an initial $4 million dollar investment in 1366 Technologies, and on Friday, announced it would make an additional $150 million dollar loan guarantee to take the company's research and development to the next level.
If projections regarding cost savings are accurate, solar may be on its way to becoming competitive with traditional fossil-fuels -- though some in the industry remain concerned about barriers still in place.
"There are two main areas of concern: price and value," said Brian Keane, president of Smart Power, a green energy marketing group. Keane explained that the primary "value" of solar "is that it's good for the environment. But quite frankly, no American actually thinks that's good value."
Keane says that U.S. consumers need to be convinced that solar is a viable proposition. "The perception is that solar is an idea from the 1970s that just didn’t work. They think it’s not strong enough to power their lives, compared with oil, coal and nuclear power."
Still, Keane added, "If we can cut the price [of manufacturing] in half, that really helps us with the value proposition to the American people."
Others point to concerns around the marketplace itself. Lew Milford, president of the Clean Energy Group, a non-profit advocacy group focused on energy and climate concerns, said that many new and innovative technologies fail because they never reach commercialization. Milford called this the "valley of death" that innovative tech companies must cross after their initial rounds of funding, and the hurdle that oftentimes prevents them from becoming scalable and reaching market potential.
Milford suggested that the problem of access to capital might be solved with something like the President's suggested--"Clean Energy Bank"--to finance clean energy initiatives, but acknowledged that the highly political climate surrounding budget negotiations would complicate its creation....."
So, in the original post above, we have solar panels that have a potential of 93% efficiency and now they've found a technique that cuts manufacturing costs in half. I would say that is definitely a game changer. This is monumental - solar enthusiasts could only have dreamed of 93% efficiency at half price. Now, if they could do the same for wind turbines. Here's one to keep an eye on
