IMEC says it has achieved >17% efficiency with thin-film silicon solar cells, and says >20% efficiencies “are definitely within reach.” Meanwhile, the research group says it is nearing the theoretical efficiency limits of Ge solar cells.  IMEC’s work involves an “i-PERC process” that replaces the Al backsurface field on a Si solar cell with thin silicon layers (<180nm) to create Al-alloyed contacts covering the entire rear side of the cell. The rear is passivated with a dielectric stack in which contact openings are realized by laser ablation. An Al contact layer is evaporated and fired in a belt-line furnace to create local back-surface fields.

Japan-based thin-film solar module maker Kaneka believes that fellow industry players can hardly survive in the photovoltaic(PV) race with crystalline silicon-based solar applications from competitors if they cannot achieve a power conversion rate of 12-13%, said company solar energy division executive officer Mikio Hatta during the recent 2007 PV Forum & Exhibition Taiwan.  Although being in the thin-film solar module business for about a decade, Kaneka has been cautious about the market trend as thin-film based materials are drawing more attention in the PV industry. With more industry players tapping thin-film solar cell production in a rapidly growing PV market, Hatta said the market is still in a state of start up and it is hard to forecast when a meaningful take off will be seen.

HelioVolt Corp of Austin, TX, USA, which has developed thin-film solar cells based on copper indium gallium diselenide (CIGS), has raised $24m from investors including Sequel Venture Partners, Noventi Ventures, and Passport Capital. This brings HelioVolt’s second-round funding to $101m, including $77m raised in August. Total funding is now $109m, including $8m from 2005’s first round.   Founded in 2001, HelioVolt is using the funds to build an $80m manufacturing plant and is considering several sites, including Austin. It has won approval from the Austin City Council for a 10-year abatement of 60% of its property taxes, after pledging to create at least 168 jobs (the firm’s current staffing is about 40).

Grand Opening on October 11 to Open a Brand New Territory for Environment. In addition, the Taiwanese government has decided to follow the global trend for developing reusable energy. Its goal is to increase solar energy supply capacity from the 2004 level of 1.2 megawatts to 21 megawatts by 2010. Photovoltaic production value in Taiwan is expected to reach NT$50 billion in 2009, up from NT$ 7 billion in 2005. (more…)

Texas has been a leader in energy for 100 years, but the state isn’t moving forward quickly enough to develop solar energy, two experts said Thursday.  “California, New Jersey, Colorado and Pennsylvania are moving more quickly than Texas” in developing solar power, said Bruce Kellison, associate director of the IC2 Institute, a think tank at the University of Texas at Austin devoted to fostering entrepreneurship and job creation.  “Greater development of solar power can bolster Texas’ weakening semiconductor and materials industries” and create jobs, Kellison said.
