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”.
Troubled thin film veteran, Energy Conversion Devices has deferred interest payments to note holders of its Senior Convertible Notes due 2013 as it continues talks with some of the holders over restructuring debt and raising funds to continue operations.
Jan Stasik has moved from his post at the parent company Wagner & Co Solar Technology to join the UK technical division. Stasik has been appointed technical manager of the solar PV and solar thermal teams, whilst also leading the training programme at the company’s Wagner Academy solar training school.
The North American Development Bank (NADBank) revealed that it is lending up to US$88.5 million to SunEdison for the development of a 20MW solar park in Picture Rocks, Arizona. This is the largest, and second, solar project financed by the NADBank. The solar park is expected to generate enough electricity for nearly 3,500 homes in the metropolitan area of Tucson.
Bloomberg is reporting that Suntech Power Holdings and Canadian Solar will be providing their solar panels to Tata Power for its US$68 million solar project. The 25MW plant in western Gujarat state will use crystalline silicon-based modules to power the solar array.
Having secured funding, Tata Power is continuing with its three-fold project in cooperation with BP Solar installing plants located in the Patan, Kutch and Mithapur areas of the state of Gujarat to be completed under its Solar Power Policy 2009.
Blaming weaker than expected revenue earnings on poor weather and other factors, First Solar lowered its 2011 revenue guidance and separately announced a restructuring of its core business groups with the exit of TK Kallenbach, President of the Components Business Group, at the end of the year. Restructuring will lead to a workforce reduction of approximately 100 associates, around 1.5% of its workforce, according to the company. First Solar revised 2011 guidance in the range of US$2.8 to US$2.9 billion, down from a prior guidance range of between US$3.0 and US$3.3 billion.
This month will see the completion of ESA Renewables’s 1.3MW commercial rooftop solar project in New Bern, North Carolina, US. ESA claims this will be one of the largest rooftop PV arrays in eastern North Carolina.
