A New Model For Ultra Efficient Solar Cell Construction

November 13, 2013 | 1 Comment

Researchers from the University of Pennsylvania and Drexel University have experimentally demonstrated a new model for photovoltaic solar cell construction with perovskite crystals.  The new idea may ultimately make photovoltaic cells less expensive, easier to manufacture and more efficient at harvesting energy from the sun. The study was led by professor Andrew M. Rappe and […]

A Claim for 100%+ Solar Cell Efficiency

December 22, 2011 | Leave a Comment

A research team at the National Renewable Energy Laboratory (NREL) report in Science the first photovoltaic solar cell that produces a photocurrent that has an external quantum efficiency greater than 100% when photoexcited with photons from the high energy region of the solar spectrum. For comparison external quantum efficiency for photocurrent is usually expressed as […]
