Solar startup Stion has found deep pockets in Asia.

The Silicon Valley-based company today said it has raised $130 million from Korea-based thin-film solar equipment maker Avaco, Korean private-equity funds, and venture capital firms. Last year, Stion took a $50 million investment from Taiwan Semiconductor as part of a larger series D round.

With today's funding, Avaco and Stion will collaborate to develop next-generation thin-film solar equipment designed to boost cell efficiency and factory output. It will also create a subsidiary in Korea and build a factory to serve Asian markets.

Stion is one of many solar companies founded … Read more

Colorado now has a slightly more aesthetic option for harnessing all that lovely Rocky Mountain sun.

Dow Solar, a division of Dow Chemical, began selling solar roofing shingles this month that may attract even the most exigent homeowner.

While there have been several pilot projects throughout the country where the Dow Powerhouse Solar Shingles have been installed since their release in 2009, Colorado is the first state where the shingles will be available for widespread sale and installation.

Dow Solar then plans to mass-market its shingles in a dozen more states, starting in California and moving across the country to … Read more

Researchers using novel materials to build photovoltaic cells say their efforts could nearly double the efficiency of silicon-based solar cells.

The cells being developed by teams from the University of Arkansas and Arkansas State University have the potential to achieve a light-to-energy conversion rate, or solar efficiency, of 40 percent or better, according to the researchers.

The photovoltaic cells are intended for use in satellites and space instruments. Currently, the silicon-based solar cells that NASA uses in its satellites and instruments have efficiencies of only up to 23 percent, according to NASA statistics.

And today it was announced that the … Read more

American solar-system manufacturer Solyndra announced today that it would suspend operations immediately and file for Chapter 11 bankruptcy protection.

More than 1,000 employees have been laid off, effective immediately.

The company offered "global economic and solar industry market conditions" as the reason. In March 2009, the company received a $535 million loan guarantee from the U.S. Treasury's Federal Financing Bank. The money was used to expand manufacturing capacity in Fremont, Calif.

Options for the company's bankruptcy include the licensing of its CIGS technology and manufacturing expertise and an outright sale of its business.

Swiss scientists have broken an energy conversion efficiency record for flexible thin-film CIGS solar cells, Empa, the Swiss Federal Laboratories for Materials Science and Technology, announced last week.

In collaboration with the Swiss solar start-up Flisom, Empa has achieved an 18.7 percent efficiency for CIGS (copper indium gallium selenide) flexible solar cells, which the lab says was made possible by mounting them on a polymer substrate. This breaks Empa's record of 17.6 percent when mounting the CIGS on steel foil substrates, according to the Swiss lab.

Solar efficiency is the amount of electricity per square inch that … Read more

Thin-film solar company Nanosolar said today it has secured sizable customer orders and it expects to match solar industry cost leaders in a few years.

Nanosolar, one of dozens of companies founded last decade to use thin-film cells to lower the cost of solar, said it has customer orders that could be as much as 1 gigawatt worth of solar panels over six years if the company meets technical milestones and ramps up volume as it projects. The panels are designed for utility-scale solar projects over 1 megawatt in size.

The contracts are a boost to San Jose, Calif.-based … Read more

SoloPower said yesterday that it has conditional commitment from the U.S. Department of Energy for a $197 million loan guarantee to build a factory in Oregon.

The company plans to start construction of a plant in Wilsonville, Ore., in the second quarter of this year. Once operating, it will be able to turn out 400 megawatts worth of solar panels per year.

The move gives San Jose, Calif.-based SoloPower the financial wherewithal to expand beyond a smaller demonstration plant in San Jose. The company has also gotten a loan and tax credits from the state of Oregon.

Intel's venture investing arm has led a $25 million investment in Berlin-based Sulfurcell, one of many companies staking a claim in the solar business with CIGS thin-film technology.

Sulfurcell makes CIGS/CIGSe thin-film solar cells that incorporate a combination of copper, indium, gallium, and selenium or sulfur. Last year, it started manufacturing in a facility able to turn out 35 megawatts' worth of panels a year.

The capital will allow Sulfurcell to scale up its production and improve the efficiency of its modules, the company said in a statement. Since 2008, the company has raised 85 million euros from … Read more

The Department of Energy has confirmed that MiaSole's thin-film photovoltaic solar modules have reached an efficiency of 15.7 percent, the company announced today.

That is an efficiency improvement of more than 1 percent since last year when the company was given a 14.3 percent efficiency rating from the DOE's 's National Renewable Energy Laboratory, according to MiaSole.

Solar panel efficiency ratings signify how much power one gets out of a solar panel per square inch, something obviously of great interest to companies and consumers evaluating which solar panels to purchase for projects.
