Solar Needs Brain Power

Other companies to apply new kinds of nanoscale manufacturing technologies to make solar cells more affordable. Miasolé of Santa Clara, Calif., said it will start volume production of its sputtered thin-film copper indium gallium selenide (CIGS) on flexible stainless-steel foil sometime later this year. President and CEO Dave Pearce said the company is "running the first vacuum system every day and now bringing up a second roll-to-roll coater" but that he is waiting for higher efficiencies before starting commercial production. Although the company's R&D tool reportedly consistently makes cells of 8 to 10 percent efficiency on 5 ft2 substrates, the production roll coaters are still running mostly in the 4 to 6 percent range. "But that's about a point higher than last month," Pearce said. "I'm comfortable we can get 8 to 10 percent this year. I think we'll get there this quarter."
