Harnessing its R&D into both c-Si and a-Si thin-film technologies, Moser Baer Solar said that it would upgrade its solar cell processes using metal and intrinsic layer semiconductor technology (MIST) to achieve average cell conversion efficiencies of 21% and join the few cell producers at the top table above 20%.
Verified by the Fraunhofer Institute for Solar Energy Systems ISE, Q-Cells said it had set new conversion efficiency records for multicrystalline and quasi-mono solar modules. A module with 60 multicrystalline solar cells, using its ‘Q.ANTUM’ cell concept was reported to have achieved 18.5% efficiency, up from a record Q-Cells claimed it had achieved of 18.1% last year. The market introduction of the Q.ANTUM solar cells and modules is planned for 2012 with pilot production at its advanced facility in Thalheim, Germany already underway.
CVD Equipment advised that its new orders in 2011 totaled over US$36 million, 44% more than the US$25 million received in 2010. New orders in the CVD/FN division of production and research systems was approximately US$30.5 million, an increase, according to CVD, of 45% compared to 2010 order levels. CVD expects high demand to continue in 2012.
Taiwan-based crystalline solar cell producer, Neo Solar Power (NSP) has reported December, 2011 revenue of approximately US$21.94 million (NT $663 million), down significantly from the previous quarter and year-on-year. Total revenue for 2011 reached approximately US$600.2 million, down from US$634.4 million in 2010.
The 38th IEEE Photovoltaics Specialists Conference (PVSC), June 3 – 8, 2012 in Austin, Texas, will be opening its registration on December 26. The event will begin with Austin Solar Day on June 3, 2012 while the remainder of the event will focus on ten technical areas including, fundamentals and new concepts for future technologies, thin-film polycrystalline photovoltaics, III-V and concentrator technologies, crystalline silicon photovoltaics, thin-film silicon-based technologies, OPV, space technologies, characterization methods, PV modules and terrestrial systems and a PV velocity forum.
JA Solar Holdings revealed that its Maple solar cells had reached an 18.5% conversion efficiency level in large volume production, with the average conversion efficiency for the Maple cells in mass production being recorded at 18%. The new record for JA Solar is noted as being higher than the industry’s standard average conversion efficiency for multicrystalline solar cells of nearly 16.8%.
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has given an exclusive patent licence to equipment specialist, Natcore Technology to use its diffused emitter technology ‘Black Silicon’ with Natcore’s liquid phase deposition (LPD) technology. The black silicon process has been claimed by Natcore scientists and NREL researchers to reduce average reflectivity to less than 1.5%, compared to current advanced antireflective coatings that are said to reduce the average reflectivity to approximately 6%. The aim is to commercialize the technology in 2012.
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.
Roth & Rau's has recently improved the cell efficiency on their heterojunction solar cells (HJT) to 21% efficiency on 156mm wafers. Presented at the European Photovoltaic Solar Energy Conference and Exhibition in Hamburg at the beginning of September this year, Roth & Rau achieved the first silicon heterojunction cell on 6 inch wafers at an efficiency rating of 20%. This result was later independently confirmed at Fraunhofer Institute for Solar Energy Systems (ISE).
Semiconductor equipment supplier, Novellus Systems is developing what it describes as conformal film deposition (CFD) technology, an atomic layer deposition process to grow conformal metal oxide and metal nitride dipole layers in the PV cells. Collaboration is being undertaken with the University of South Florida (USF), to study the precise engineering of solar cell interfaces via a National Science Foundation (NSF) grant.
