Stacked Solar Cell Attains 43.9% Efficiency

Stacked Solar Cell Attains 43.9% Efficiency

Semprius has manufactured a four-junction, four-terminal stacked solar cell in collaboration with scientists at the University of Illinois/Urbana-Champaign and researchers at Solar Junction. Initial trials yielded measured efficiencies up to 43.9 percent. The stacked solar cell is comprised of a three-junction microcell that is stacked on … Read more…

Solar Cells Operating at Double the Usual Output

Solar Cells Operating at Double the Usual Output

Solar cells that may be able to convert up to half of the sunlight that falls on them into electricity are undergoing tests in North Carolina. Even the best cells today only operate at 25 percent efficiency. John Rogers, of the University of Illinois, Urbana-Champaign … Read more…
