New World Record for Tandem Polymer Solar Cell Efficiency

  “Scientists boosted the significance of tandem polymer solar cells by successfully testing cells with low-bandgap polymers that achieved certified conversion efficiencies of 8.62 ± 0.3% with respect to standard terrestrial reporting conditions,” the National Renewable Energy Laboratory (NREL) announced today. “Further, after the researchers incorporated a new infrared-absorbing polymer … [continued]

High-Efficiency Solar Cells Getting More Efficient, Cheaper

  Solar Junction is a 4-year-old company spun out of Stanford University that designs high-efficiency, multi-junction solar cells for concentrating photovoltaic (CPV) solar collectors. The National Renewable Energy Laboratory recently certified that its solar cells can operate at 40.9% efficiency, a significantly higher efficiency than typical silicon solar cells that … [continued]
