New Approach Aims to Slash Cost of Solar Cells

March 5, 2012

Solar-powered electricity prices could soon approach those of power from coal or natural gas thanks to collaborative research with solar start-up Ampulse Corporation at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL).

Silicon wafers account for almost half the cost of today's solar photovoltaic (PV) panels, so reducing or eliminating wafer costs is essential to bringing prices down.

Current crystalline silicon technology, while high in energy conversion efficiency, involves processes that are complex, wasteful, and energy intensive. First, half the refined silicon is lost as dust in the wafer-sawing process, driving module costs higher. A typical 2-meter boule of silicon loses as many as 6,000 potential wafers during sawing. Second, the wafers produced are much thicker than necessary. To efficiently convert sunlight into electricity, they need only one-tenth the typical thickness.

NREL, DOE's Oak Ridge National Laboratory (ORNL), and Ampulse have teamed on an approach to eliminate this waste and dramatically lower the cost of the finished solar panels. The aim is to create a less expensive alternative to wafer-based crystalline silicon solar cells.

By using a chemical vapor deposition process to grow the silicon on inexpensive foil, Ampulse is able to make the solar cells just thick enough to convert most of the solar energy into electricity. No more sawdust — and no more wasting refined silicon materials.

Straight from Pure Silicon to High-Quality Crystal Silicon Film

NREL developed the technology to grow high-quality silicon.

ORNL developed the metal foil that has the correct crystal structure to support that growth.

And Ampulse is installing a pilot manufacturing line in NREL's Process Development Integration Laboratory (PDIL), where solar companies test their latest materials and processes.

With knowledge and expertise acquired from the PDIL pilot production line, Ampulse plans to design a full-scale production line to accommodate long rolls of metal foil.

The Ampulse process "goes straight from pure silicon-containing gas to high-quality crystal silicon film," said Brent Nelson, who runs the PDIL at NREL. "The advantage is you can make the wafer just as thin as you need it — 10 microns or less."

Most of today's solar cells are made out of wafer crystalline silicon, though thin-film cells made of more exotic materials like gallium, arsenic, indium, arsenide, cadmium, and tellurium are making a strong push into the market.

The advantage of silicon is its abundance, as it is derived from sand. Its disadvantage is that purifying it into wafers suitable for solar cells is expensive and energy intensive.

Manufacturers add carbon and heat to sand to produce metallurgical-grade silicon, which is useful in other industries, but not yet suitable for making solar cells. This metallurgical-grade silicon is then converted to pure trichlorosilane (SiCl3) or silane (SiH4) gas.

Typically, the purified gas is converted to create a silicon feedstock at 1,000 degrees Celsius (°C). This feedstock is melted at 1,414°C and recrystallized into crystal ingots that are finally sawed into wafers. Think of it as the Rube Goldberg approach to creating a solar cell.

Instead, the Ampulse process backs up two steps. Rather than create a feedstock, it works with the silane directly and grows just the needed silicon right onto a foil substrate.

Combining NREL's Deposition Technique with ORNL's Textured Foil

A team of NREL scientists including Howard Branz and Chaz Teplin had developed a way to use a process called hot-wire chemical vapor deposition to thicken silicon wafers with perfect crystal coatings. Using a hot tungsten filament much like the one found in an incandescent light bulb, the silane gas molecules are broken apart and deposited onto the wafer using the chemical vapor deposition technique at about 700°C — a much lower temperature than needed to make the wafer. The hot filament decomposes the gas, allowing silicon layers to deposit directly onto the substrate.

Armed with this new technique, Branz and Teplin searched for ways to grow the silicon on cheaper materials and still use it for solar cells.

They found the ideal synergy when visiting venture capitalists from Battelle Ventures asked them whether they could do anything useful with a breakthrough at ORNL called RABiTS (rolling assisted biaxially textured substrate). It was just the opportunity the two scientists had been seeking.

If metal foil is to work as a substrate, it must be able to act as a seed crystal so the silicon can grow on it with the correct structure. The RABiTS process forms crystals in the foil that are correctly oriented to receive the silicon atoms and lock them into just the right positions.

NREL and ORNL worked to combine their technologies using a small amount of funding from Battelle Ventures. Using the right intermediate "buffer layers" to coat the foil substrates, the researchers were able to replicate the desired foil crystal structure in the silicon layer grown over metal foil (epitaxial growth).

Establishing Ampulse Corporation

With a commitment to develop the new technology in cooperation with the two national labs, Battelle Ventures and Innovation Valley Partners joined forces to form Ampulse. Initially, Ampulse had very few employees and no offices — just a name, an idea, and a commitment to develop the technology via the unique instrumentation and scientific expertise at the two national labs.

The company then established a $500,000 cooperative research and development agreement (CRADA) with NREL and a similar agreement with ORNL.

Ampulse also received a total of $900,000 from DOE's Technology Commercialization and Deployment funds at NREL and ORNL. Because Ampulse was started as a company with very low overhead, nearly all its initial funding went toward research efforts at NREL and ORNL.

"Our initial technology success from those funds enabled Ampulse to raise two rounds of venture capital," Branz said.

The company now has 13 employees and six full-time consultants and is currently working with 22 sponsored researchers from two national labs. The first employee at Ampulse, Steve Hane, remains its CEO.

A Giant Step Toward the $1 per Watt Goal?"We have the potential to produce a 15%-efficient solar cell at less than 50 cents per watt with a fraction of the capital investment of other venture-funded PV companies," Hane said. "And that's due to our R&D collaborations with the national labs." Hane said the unique relationship between the national labs and venture capitalists should be a model for future technology transfers to the private sector.

Recently, with its SunShot Initiative, DOE challenged researchers to lower the cost of solar energy by two-thirds to $1 per watt installed. By eliminating costly silicon wafers — but still using silicon as the core material — the Ampulse approach has the potential to meet this target.

"The trick is to get as good material quality as you have in a wafer," Teplin said. "We're using our existing knowledge of how to grow silicon directly from a gas phase onto these metal foils."

Production Line Features Vacuum Chambers and Quartz LampsThe production line being installed at NREL's PDIL consists of a half dozen cube-like vacuum chambers where foils are overcoated with buffer and silicon layers to fabricate solar cells. It was built to Ampulse's specifications by Roth & Rau Microsystems of Germany.

The new production system will also exchange samples with other NREL research and analysis equipment in the PDIL. NREL's "wafer replacement tool" will be connected to the Ampulse system and will have a robot that can retrieve samples while maintaining vacuum, preventing exposure of the sample to air.

To fabricate solar cells, metal foils are loaded into the Ampulse system, where quartz lamps heat them to a temperature of 850°C. First, the foils are coated with the necessary buffer layers. Then, the samples are transferred to a specially designed chamber where the key silicon layers are grown. The silicon is then exposed to atomic hydrogen to improve its electronic properties. Finally, solar cell junction and electrical contacts are developed.

"With this new tool, we will be able integrate NREL and ORNL technologies seamlessly and quickly," Teplin said. "Further, with access to all of NREL's other PDIL capabilities, we really expect technological progress to accelerate."

Branz summed up: "The main thing is that we can grow high-quality silicon layers very fast and without putting much energy into the process. That means the solar cells can turn out much cheaper than the wafer-based cells."

"Our process goes directly from gas to the epitaxial silicon phase, bypassing the growth and sawing phase," Ampulse's Director of Planning and Logistics, Mike Colby, said. "We made it large because we needed to demonstrate the scalability of the system."

"To accelerate time to market, we need to maximize the cycle speed," Colby added. "The goal is to achieve the crystal silicon performance that until now focused on thicker wafers — and without having to use a 1,400°C furnace."

As skilled technicians tweaked the knobs of the potentially game-changing prototyping line, Colby said, "We've had good luck and a good relationship with NREL. The aim of NREL, and of the PDIL, is to work with the needs of business and help accelerate commercialization of new technologies. This definitely does that."

The 6 Secret Weapons of CommercializationA boot camp for nanotechnology and industry.

By Scott E. Rickert

Feb. 24, 2012

Let's face it -- new product development always demands "courage under fire." And if there were a medal of honor in the category, complex new technologies like nanotech would surely qualify for being "above and beyond the call of duty." Still, with the current emphasis on advanced manufacturing for the American economy, there's never been a better time for action. After 20+ years in this business, I've gained some battlefield wisdom. Whether you're a nanotechnology company or a mainstream manufacturer looking to incorporate nanotechnology into products, these secret weapons can help you avoid some battlefield casualties.

1.Send out more scouts. It's hard to know when a technology and a product will find the perfect match. So nanotechnologists -- send samples, do product tests, whatever it takes to start the ball rolling. My R&D labs are constantly coating prospects' products, developing test protocols, trying something new to work through a compatibility or performance question. And manufacturers? Talk to as many people and companies as you can -- you may discover possibilities that weren't even be on your radar.

2. Meet with your generals. As I said, a buyer-vendor relationship doesn't really work in nanotechnology yet. A partnership that brings the top decision makers together is your best bet. Be sure it includes all the disciplines: R&D, Manufacturing, Marketing, and even some C-Level personnel make the best task force.

My deal-breaker? Having someone with control of the purse strings at the table. I've found that people without budgetary control are often focused on a successful project or process. People with bottom line responsibility insist on a successful product -- because that's where money invested delivers payback... or not.

3. Keep the battle plans flexible. Maybe you're a manufacturer who's accustomed to being a "buyer" working with "vendors." That may hold you back in the still-developing nanotechnology market. I've seen the best success from true partnerships, but we also see plenty of joint development, tech sharing, market sharing, and even licensing. There are many ways to win a market if you can adapt your battle plans.

4. Embrace guerilla warfare. It's fine to look for the big wins. Somebody needs to be chasing the silver bullet -- that wind-powered car battery that dances on the head of a pin. But you can gain ground with small skirmishes, too. There's likely to be a market-ready nanotechnology -- or two or three -- that could add incremental value tomorrow. For example, a Nanofilm self-cleaning film for automotive glass was "discovered" as a snow-shedding coating for solar panels and a fingerprint guard for sandblasted architectural glass.

5.Who's ready for hand-to-hand combat? Look for partners thinking beyond a "magical material." Be sure everyone has gotten out of the lab and faced the challenges required by the real world. There's a big difference between making batches of a formula in the lab, running it in a test environment and needing tanker loads for full production.

6. Never retreat. To quote Thomas Edison, one of the winning-est generals on the invention battlefield, "The most certain way to succeed is always to try just one more time." I couldn't agree more. So tweak, reformulate, rethink. Try another path, another formula, another idea. Always keep going -- it's the only way to get ahead.
