Solar Junction, a developer of multi-junction solar energy cells for the concentrated photovoltaics market, says it has set a new record for the energy efficiency of a commercial-ready production solar cell.
The power conversion efficiency of Solar Junction's cells was measured at 44% at 947 suns, beating the company's previous record of 43.5% at 418 suns, which was set in April 2011. Both records were verified by the National Renewable Energy Laboratory (NREL), Solar Junction says.
