Massachusetts, United States [RenewableEnergyWorld.com] Kopin Corp. announced that it has been selected for the award of a US $600,000 solar cell development contract from NASA. The contract is the second phase of a Small Business Technology Transfer (STTR) program to develop indium nitride (InN)-based quantum dot solar cell technology.
Kopin’s quantum-dot nanostructures allow the spectral response and operating voltage of a solar cell to be tailored in ways that are not possible with bulk semiconductor materials. In particular, the wide range of energies accessible to InN-based materials provides unique flexibility in designing quantum-dot solar cell structures. This technology could enable photovoltaic power systems for future NASA space exploration missions to operate in extreme environments with high temperature and radiation exposures.”
“The goal of this STTR program is to develop high-efficiency solar cells that are resistant to extreme conditions while achieving high solar electric power conversion efficiency,” said Dr. Roger Welser, Kopin’s Director of Technology and New Product Development. “The advanced patent-pending solar cell structure incorporating InN-based nanostructures can harness a very large fraction of the solar spectrum while minimizing the effects of high temperatures and high-energy radiation.”
