Sharp announced that it will start full-scale mass production of its crystalline Si solar cells with a cell conversion efficiency of 20% in 2010.  “It is going to be more powerful than any other residential crystalline silicon solar cell,” said Toshishige Hamano, executive vice president of Sharp Corp.

Researchers have developed some of the tiniest solar cells ever made and said on Thursday the organic material could potentially be painted on to surfaces.  So far, they have managed to pull 11 volts of electricity from a small array of the cells, which are each just a quarter of the size of a grain of white rice, said Xiaomei Jiang of the University of South Florida, who led the research.

suniva_begins_production_announces_plans_for_second_solar_cell_line/

Suniva confirmed that it has successfully begun production on its 32-MW monocrystalline solar-cell production line in Norcross, GA. The company also said that it plans to install a second fab line next year with double the manufacturing capacity of the first line and will continue its turnkey partnership with centrotherm photovoltaics.  Once the new line is completed in mid-2009, the company will have a total cell-production capacity of 96 MW-peak, with both of the initial lines combining centrotherm integrated equipment and Suniva’s proprietary fabrication techniques. The cell manufacturer said it plans to push the capacity in its first factory to about 175 MWp by early 2010. (more…)

Richard Swanson, SunPower’s President, says there is no equivalent of Moore’s Law in solar, but other things work in the industry’s favor.

Solar CEOs like to complain these days about the lack of capital and the difficulty of getting their companies off the ground.  They should talk to Richard Swanson. As a professor of electrical engineering at Stanford in the 70s and 80s, he emerged as a leader in solar research. He co-founded SunPower back in 1985 to capitalize on the growing interest in alternative energy. Still, the company lived from project to project until Cypress Semiconductor invested $150 million into the company in 2002.

Kyocera Corporation (President: Makoto Kawamura) today announced plans to build a new large-scale solar cell manufacturing facility. The new plant, located in Yasu City, Shiga Prefecture, Japan, will be the Kyocera Group’s largest manufacturing facility in Japan.  Construction of the plant is planned to start in early 2009 and be completed by year’s end, with production scheduled to begin in the spring of 2010. Combined with Kyocera’s existing Yohkaichi plant, the new facility will permit the company to more than double its annual production of solar cells aEUR- from this year’s projected output of 300 megawatts (MW) to 650MW by March 2012. The new plant will manufacture Kyocera’s new back-contact cell, which yields 18.5% energy conversion efficiency. (more…)

Currently, solar cells are difficult to handle, expensive to purchase and complicated to install. The hope is that consumers will one day be able to buy solar cells from their local hardware store and simply hang them like posters on a wall.  A new study by researchers at the UCLA Henry Samueli School of Engineering and Applied Science has shown that the dream is one step closer to reality. Reporting in the Nov. 26 edition of the Journal of the American Chemical Society, Yang Yang, a professor of materials science and engineering, and colleagues describe the design and synthesis of a new polymer, or plastic, for use in solar cells that has significantly greater sunlight absorption and conversion capabilities than previous polymers.

You never know where basic research may lead. For decades materials scientists have been experimenting with a corkscrew-like polymer structure called a gyroid. Now an international team of researchers has shown that the gyroid structure can be used to “self-assemble” a low-cost photovoltaic cell. The idea could lead to more economical solar collectors and more efficient fuel cells. (more…)

Sharp of Japan, Enel of Italy and a third manufacturer will invest more than $2.6 billion in Italian solar power ventures to tap growing demand for cleaner energy.  Top solar power firms are hurrying to expand capacity even as the sector smarts from a worsening global economy, which is drying up financing for new ventures and forcing smaller solar power firms to push back investment.  Sharp, the world’s No.2 maker of solar cells after the German company Q-Cells, said it and Enel planned to spend about ¥100 billion, or $1.05 billion, to set up solar power generating plants in Italy with a total generating capacity of 189 megawatts by the end of 2012.

Sharp said Thursday it’s in talks with Italian utility company Enel to set up a European joint venture to produce solar panels – a move that highlights the Japanese electronics company’s ambitions in this key green business.  “We are considering cooperation with Enel SpA to jointly produce solar cells,” Sharp Corp. (other-otc: SHCAY.PK – news – people ) spokeswoman Miyuki Nakayama said, while declining to elaborate. Sharp will give details at a news conference later in the day, she said.

New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers at MIT.  Using computer modeling and a variety of advanced chip-manufacturing techniques, they have applied an antireflection coating to the front, and a novel combination of multi-layered reflective coatings and a tightly spaced array of lines — called a diffraction grating — to the backs of ultrathin silicon films to boost the cells’ output by as much as 50 percent.
