Darryl Nakamoto has resigned from his position as Hoku's chief financial officer. Nakamoto, who also served as Hoku's treasurer and secretary, will remain at the company until March 31, 2012 to help the search for his successor and assist with the transition.
Dye-sensitized solar thin-film specialist, Dyesol has claimed a 15% increase in the efficiency performance of large DSC strip cells has been achieved, bringing industrial DSC efficiency up from 6.9% to 8% in 2011. The increase in efficiency results were said to come from improvements in materials and structural design elements.
Financially challenged silicon metal supplier, Timminco has tapped Bank of America for the remaining US$2.9 million of a revolving credit facility, resulting in the company having to pursue alternative sources of financing. The Canada-based materials producer recently reported third quarter sales of US$28.6 million and a net loss of US$2.4 million.
Avancis has said that its new state-of-the-art CIS thin-film module production plant has begun ramping. Construction of the 100MW capacity facility started in June 2010 and enables the company to offer new products, boost efficiencies and lower costs, compared to its previous 20MW facility. The number of employees at Avancis is set to double from the current 250 to almost 500.
Market research firm, IHS iSuppli has undertaken its first product teardown and analysis within the PV industry. An Aurora PVI-4.2-OUTD-S-US Inverter from Power-One was used in the teardown, which IHS iSuppli said provided a path-setting benchmark for cost reduction within a sector of the industry expected to undergo rapid price erosion, inline with other industry sectors such as polysilicon, wafers, cells and modules.
IDC Energy Insights has released its findings for the PV module market over the next four years. The firm’s encouraging figures are forecasting that on a global scale, PV module shipments will rise from their current 22.7GW level (2011) to 43.8GW in 2015.
The US Department of Energy’s National Renewable Energy Laboratory advised that it recently validated Semprius’ triple-junction cells at greater than 41% efficiency at a concentration of 1,000 suns – said to be one of the highest efficiencies recorded at this concentration. The North Carolina company makes its cells from gallium arsenide with the lenses laying claim to concentrating the sunlight onto the small cells 1,100 times.
Two years of hard work has culminated in the development of a prototype for a next generation solar PV device. It will be submitted to the National Renewable Energy Laboratory (NREL) in early 2012 for certification. The NGD technology uses a novel approach combining a barrier oxide layer with a patent-pending absorber layer, replacing the traditional semiconductor layer used in crystalline silicon and thin-film PV.
GreenVolts has re-emerged with seeming aplomb from the disaster of 2009 with its new CPV system that it has branded as the PV industry’s “first complete and fully integrated solar system”.
