Two new solar research projects at Arizona State University will receive funding from the U.S. Department of Energy, the SunShot Initiative announced today. Both projects, funded under the Small Innovative Projects in Solar(SIPS) program, have the potential to dramatically reduce solar energy production costs.
The SunShot Initiative is designed to accelerate the market competitiveness of solar energy by targeting production cost reductions and increased solar deployment, with a 2020 target cost for utility-scale solar technologies that is roughly equal to electricity generation from fossil fuels.
Current photovoltaic modules have efficiencies of about 15-20 percent. Principal Investigator Zachary Holman, an ASU assistant professor, and Co-investigator Roger Angel, a Regents’ Professor at the University of Arizona, have proposed using an unconventional, tandem system to raise efficiency to greater than 30 percent.
