Network for Photovoltaic Technology

Network for Computational Nanotechnology at Purdue University to lead effort to improve solar cells through modeling and simulation Purdue University will lead a new research center to improve photovoltaic solar cells as part of a national effort to bring alternative energy technologies to the marketplace.The work is funded by the Semiconductor Research Corporationa university-research consortium for semiconductors and related technologiesThe SRC has established a $5 million energy research initiativeteaming companies with university research centers to work on alternative energy technologies.The new Network for Photovoltaic Technology will be led by Ashraf Alamprofessor of electrical and computer engineeringand Mark Lundstromthe Don and Carol Scifres Distinguished Professor of Electrical and Computer EngineeringWork in the centerbased at the Birck Nanotechnology Center at Purdue's Discovery Parkwill address performancecostreliability and manufacturing challenges of photovoltaic cellswhich convert sunlight into electricity."The center will take advantage of Purdue's extensive modeling and simulation expertise and our national Network for Computational Nanotechnology,said Richard BuckiusPurdue's vice president for research"The NCN provides analytical models and simulation tools for photovoltaic manufacturersmuch as Purdue has done for the semiconductor industry."Photovoltaics is a clean energy sourceand few other power-generating technologies have as little environmental impactHoweverthe technology faces several hurdlesprimarily costs relating to power generation and transmissionResearchers are working to develop new cells that are less expensive to manufacturewhich would reduce costs associated with photovoltaics.In addition to the photovoltaics centerthe initiative includes a smart grid research center at Carnegie Mellon University to support the incorporation of renewable energy resources and provide modelingsimulation and control tools needed to manageoptimize and secure the power grid.Research in the Purdue-based center will initially address the need for new modeling and simulation tools to support the development of improved photovoltaic devices.Since the 1960sthe semiconductor industry has been developing advanced computational models and simulationswhich have become critical for the design of electronic devices and have enabled industry to develop new technologies and products."We want to do the same thing for photovoltaics,Lundstrom said"This will be the first center to emphasize the role of models and simulations in this areaand we will seed knowledge gained in this work to industry and other research centersWe're getting in on the ground floor."The work will include research to precisely characterize the properties of materials used in photovoltaic cells in efforts to better understand the physics involvedComputational models and simulations will enable researchers to test concepts and reliability and also to accelerate the aging of solar cells to see how long they will last."Any estimate of the cost of photovoltaics assumes the cells will last for 20 to 30 yearsbut what if they're more likely to last 60 yearsThe cost landscape among competing clean technologies can be altered dramatically as a result,Alam said.The work builds on previous modeling research led by Alam and Lundstrom to develop advanced models for predicting the performance and reliability of new designs for silicon transistorsThe same sort of modeling will now be used for photovoltaicsThe initiative also aims to train and educate studentsproviding them with the expertise and skills needed to transition these new methods into the marketplace.The work is associated with an interactive website called nanoHUB.orgwhich makes available scientific simulationsseminarsinteractive courses and other specialized nanotech-related materialsIt is operated by the NCNa six-university network funded by the National Science Foundation and based at PurdueThe Intel Foundation also provides support. $(document).ready(function({ if$("#msgSubject"!null &$("#msgSubject"!undefined{ $("#msgSubject").val('');
