The U.S. DOE announced that it will invest up to $13.7 million over the next three years in 11 projects run by nine universities that will develop advanced solar photovoltaic (PV) manufacturing processes and products.
With a minimum university and industry cost share, up to $17.4 million will be invested in these projects. The chosen universities include Arizona State University, the California Institute of Technology, the Georgia Institute of Technology, the Massachusetts Institute of Technology, North Carolina State University, Pennsylvania State University, the University of Delaware, the University of Florida, and the University of Toledo. Each of the 11 universities will work with an industry partner that will help transition the discoveries to the marketplace.
All of the projects will involve researching ways to make high-performance solar cells more effective by using different metals, alloys, and cell designs. One project will try to reduce bottlenecks in the qualification testing for concentrating solar cells; two will explore better methods of building crystalline silicon solar cells; four will explore solar cells built from thin films of semiconducting materials; one will combine an organic (plastic) semiconductor with arrays of titanium dioxide nanotubes; and two will try to create multijunction solar cells by depositing thin layers of materials (amorphous silicon and indium phosphide) onto silicon solar cells.
Multijunction solar cells convert more sunlight into electricity by employing multiple layers of photovoltaic material, with each layer capturing a different part of the solar spectrum. While current commercial multijunction solar cells have three active layers, the project conducted by North Carolina State University and Spectrolab Inc. will involve building a four-junction solar cell with a targeted efficiency of 45%, that is, the cell would be able to convert 45% of the sunlight hitting it into electricity.
