Professor Tonio Buonassisi’s Laboratory for Photovoltaics Research, in partnership with CaliSolar, Inc. and BP Solar, Inc., was recently awarded funding by the U.S. Department of Energy for a project entitled “Defect Engineering, Cell Processing, and Modeling for High-Performance, Low-Cost Crystalline Silicon Photovoltaics.” This project will characterize defects and engineer their distribution within a solar cell to close the efficiency gap between industrial multicrystalline and high-efficiency monocrystalline silicon cells, while preserving the cost advantage of these low-cost, high–volume substrates. The project is targeting 18-22% efficient cells at manufacturing costs of less than $1 per peak watt. DOE will provide up to $1.5 million for this approximately $1.9 million project.
