GE: Solar business is our 'next wind'

CAMBRIDGE, Mass.--General Electric plans to give its solar business a charge within two years by introducing panels with the same solar cell material used by industry cost leader First Solar.

In 2011, the energy giant expects to produce solar panels made with cadmium telluride, a thin-film solar cell material, Michael Idelchik, vice president of advanced technologies at GE Global Research, said here Wednesday at the EmTech conference. The company now sells solar panels that use silicon solar cells, but its long-term bet is on thin-film--and specifically cadmium telluride--because it offers the cheapest cost per watt, he said.

Last year, … Read more

BioSolar marks its biomass turf with patent app

BioSolar has filed a patent application for a new type of backing for photovoltaic cells.

A backsheet is the bottom layer of a photovoltaic cell used by solar manufacturers to protect the cell from moisture, temperature fluctuations, and the elements.

BioSolar's BioBacksheet-A, a new addition to the company's line of backsheets, consists of a sheet of aluminum foil sandwiched between two layers of polymer made from renewable plant sources. The aluminum used in the sheets is also 100 percent recyclable.

The company announced that it was developing plant-based plastics for solar-cell components, which included the use of cotton and castor beans, … Read more

Solar tiles that offer style

Correction at 7:20 a.m. PDT June 23: The energy production of the tiles has been fixed. The tiles can generate 860 kilowatt hours per square (or per 100 square feet) annually in an area with "5.8 peak sun hours" per day.

Will a better aesthetic tempt more people into going solar? SRS Energy is betting on it.

The company has partnered with US Tile, a leading manufacturer of Spanish, slate, and shake roof tiles, to design solar panels with the exact same shapes as their clay counterparts.

The result is solar tiles that can be … Read more

Solar start-up scores with series of tubes

Solyndra, a start-up making thin-film photovoltaic systems, has secured $600 million in funding.

It's additionally secured $1.2 billion in contracts from clients in the U.S. and Europe, the Fremont, Calif.-based company revealed Tuesday.

What start-up gets that kind of funding and client promise? Basically, one that's invented thin-film solar panels shaped like old-school fluorescent lightbulbs.

Since 2005, Solyndra has quietly been developing a proprietary CIGS-based thin film photovoltaic (PV) system and a staff of more than 500 employees.

CIGS is a material that includes a combination of copper, indium, gallium, and selenide. It's now … Read more

Money shines on thin-film solar maker SoloPower

If you need more proof that thin-film solar cells is where the action is going, take a look at the money flow.

SoloPower is raising almost $200 million to ramp up manufacturing of its thin-film solar cells, according to a report in VentureWire picked up by other media outlets.

The San Jose, Calif.-based company makes cells from CIGS, a combination of copper, indium, gallium, and selenide which a number of solar companies are betting can undercut traditional crystalline silicon.

Thin-film solar cells, from CIGS or other materials, are less efficient at converting sunlight to electricity but use far less … Read more

Intel Capital spreads its solar bets with Sulfurcell

Intel's venture capital arm, Intel Capital, on Wednesday said it has invested in German thin-film solar cell manufacturer Sulfurcell.

Intel Capital led the $133.7 million (85 million euro) round with a $37.7 million contribution. The money will be used to expand the company's existing production, which started in 2005.

The announcement follows the spin-off last month of SpectraWatt, a manufacturer of silicon solar cells, from Intel.

Sulfurcell, by contrast, is an expert in thin-film solar cells made from a combination of materials in the CIS/CIGSe (Copper-Indium-Sulfide/Selenide) family of chemicals. The company was spun out … Read more

Who will make CIGS work for the solar sector?

I've been saying for a while, that with enough money, someone is bound to crack the CIGS nut in thin film, and deliver the cleantech sector another First Solar (NASDAQ:FSLR) like renaissance for the always around the corner technology.

That's not because it's easy, or even because it's a good idea to try, but when well over a billion dollars in investment pours into a given technology, something is bound to come out the other side - eventually. A seductively high efficiency potential technology with very low potential materials costs, CIGS has been just over … Read more

FTL Solar gets funds for power-generating buildings

FTL Solar on Wednesday announced it has raised capital to make flexible solar cells for buildings that generate electricity.

The company envisions that its structures, called PowerMods, can be used as battery-charging stations, parking lot canopies, disaster relief shelters, remote medical stations, and for military bases.

The company said that Terra Firma Capital Group, the Josh Mailman Foundation, and individual investors completed the first phase of a planned $50 million funding it expects to finish by the end of the year. It was also awarded a $200,000 matching grant from the New York State Energy Research Development Authority.

FTL … Read more

Abu Dhabi's Masdar bets $2 billion on thin-film solar

Masdar, an Abu Dhabi-based clean-technology initiative, said on Wednesday that it will invest $2 billion to manufacture thin-film solar cells.

The money will significantly boost global solar cell production, potentially bringing prices down. It's also a major bet on thin-film solar cells, which use less material than traditional silicon.

Analysts expect thin-film cells, made from a variety of materials, to become a significant portion of solar cell manufacturing and ratchet up competition on incumbent suppliers.

The Masdar Initiative, which is building a "green city" in Abu Dhabi, said in a release that an initial $600 million will … Read more
