This indeed is quite informative topic. Authors of these topics are not expert with decades of experience, but well informed EE. Data may not be very accurate like that of IEEE Transaction, but contents gives direction of new develeopment and they are very interesting. This is true for lot of content on web. So, if you have better data, you may correct autor, but it should be in very mild voice. One day you may be worng, and do not expect all other EE to reprimand you for the same.

Dear Charles,

It is in fact a very big deal who and which technology has the highest efficiency for mass-produced thin films. Just because other two-bit blogs made the same mistake does not give this blog any excuse for printing inaccurate information.

Also, as to your "larger point": GE's market share will most certainly go up... because they start from zero. But there is no guarantee that GE will grab a significant share of the PV panel market, particularly as First Solar has been recently lost market share to Chinese crystalline silicon with the same technology and the lowest cost per watt in the industry.

There is also the significant factor of competition within the thin film space from CIGS (or CIS), particularly CIS coming from Solar Frontier's new 900 MW factory in Japan. Because of that factor, it is very important which thin film technology has the highest efficiencies, the lowest costs, and other market factors.

The U.S. market share of solar panel manufacturing IS NOT going up. The U.S. maintains a overall PV industry trade surplus due to sales of manufacturing equipment and polysilicon exports, which is the point of the GTM/SEIA report. The U.S. share of PV panel (module) manufacturing IS GOING DOWN.

You would not know any of that from reading this article. And this is growing tiresome. Read the report, it's free.

C. Roselund,

>>>I am unsure whether GE is claiming to have the highest efficiency mass-produced cadmium telluride modules on the market, or the highest efficiency mass-produced thin-film modules.

The problem is GE worded their press release as claiming, "world's most efficient thin film solar panel."  Just+ google that phrase (add the word GE) and you will get hundreds of hits all with the title "GE Builds the Most Efficient Thin-Film Solar Module Ever" from pretty impressive news sources and trade journals.  It looks like GE meant to claim the record only for CdTe panels, but it's not only EBN which reported their claim at face value as stated.  Unless you are going to start e-mailing hundreds of publications, the (mis)information is already out there.

I thought the focus of the post here was the potential increase in market share that the solar panel industry, particularly GE, may grab in the near future.  To split hairs over whether there should be a qualifier that GE holds the record only for cdTE cells and not all cells is a quibble that does not change the main idea that GE's market share and the US market share in general is going up.

Dear Charles,

There are multiple thin-film PV technologies. Two of them are cadmium telluride and CIGS.

I am unsure whether GE is claiming to have the highest efficiency mass-produced cadmium telluride modules on the market, or the highest efficiency mass-produced thin-film modules. It is also possible that they are being intentionally vague, as 12.8% is, again, simply not the highest efficiency thin-film module. In the article Ariella cites it is clear that they are talking about cadmium telluride. Ariella is not - and thus misinformation is born.

CIGS modules have achieved higher efficiencies in mass production, and both technologies have acheived higher efficiencies under lab settings. GE may well have the highest efficiency for mass-produced cadmium telluride - the highest I have heard from First Solar is 12.6%.

As for Q-Cells and their 13.4% efficient mass produced thin film modules, the release is here, with efficiencies verified by Fraunhofer ISE: http://www.q-cells.com/en/company/investor_relations/corporate_news/29032011_qcells_achieves_with_134_new_efficiency_world_record_for_cigs_thin_film_solar_module_out_of/index.html?pr=594

As for the excuse about not having access to the site, Ariella: Citation or no citation, the statement you wrote is inaccurate. If you insert the words "cadmium telluride", then I have no argument against its accuracy. Have your editor fix it. It is not in anyone's interest to have false or misleading information floating around the internet.

Also, I find it terrifying that you have taught on the subject of journalism, as you did not do a minimum of research to assure that you had written an accurate article - like actually reading the SEIA/GTM report.

For those seeking accurate information about the solar industry, I recommend my publication, Solar Server: http://www.solarserver.com.

Judging from the recently reported failure of Solyndra,

http://www.washingtonpost.com/politics/solyndra-solar-company-fails-after-getting-controversial-federal-loan-guarantees/2011/08/31/gIQAB8IRsJ_story.html

A company heavily touted by the Obama administration and a recipient of plenty of our tax $, it looks like greeen energy is a long way off from being an economically feasible alternative in the US.

>>>GE's modules are not the highest efficiency thin film modules on the market

I think it's pretty clear that the post is based on GE's press release, which stated:

"GE (NYSE: GE) today announced that a full-size, thin film solar panel developed by the company has been independently certified as the most efficient ever publicly reported milestone for the technology."

So in a nutshell, C. Roselund, just to clarify, you are saying that GE pulled one over on everyone and this is not true?

@electronics862 You mention on particular incident, but there are also other reasons why the US is looking to get less dependant on fossil fuels for energy. One is not to be so affected by the fluctuations in price of oil, but another is also concern for the effects on the environment, particularly in certain areas of the country.

I cannot edit what went up because I do not have adminstrative access to the site. I concede to you on the first point for one word that should be changed in the body, but what I wrote about the status of GE thin film panels is an accurate representation of the sources cited for that information. The embedded link makes it clear that it is based on other authorities, not my own opinion.   Now that is something I am an expert on --  the difference between properly cited material and -- a subject I've taught for years.  The difference in convention online that you may not be used to is using the link instead of a footnote. BTW I contacted the lab to ask about their findings. But really the point of this blog was not whether or not GE broke a record but to look at its plans to do more with solar power in the US.

OK, so let me see if I have this right. Your article contains inaccurate statements, which you know now are inaccurate, and are refusing to change, or issue a correction because it's only a couple of lines?

The first line you admit is incorrect. Second, your article states that "In April, GE succeeded in attaining 12.8 percent efficiency on its thin film solar panels -- better than any other such panels on the market." You say thin film, and then "any other such panels". GE's modules are not the highest efficiency thin film modules on the market, so this is a second inaccurate statement.

But also you have done no original research, did not even read the report that you are "reporting" on, and admit that you cribbed other articles as your defense for these inaccurate statements - instead of doing what a journalist would do, and going to the source NREL materials.

I am afraid this is a stunning example of why so much of what is on the internet posing as journalism is not journalism at all.

US really investing resources in solar energy as they realized oil resources will be gone in next few years. After the BP spill over incident US invested billions of dollars in both university research and industries to come up efficient way of storing solar energy.
