USA Company raises thin-film PV module efficiency record to 2015-06-30
First Solar Inc of Tempe, AZ, USA has raised its world record for cadmium telluride (CdTe) photovoltaic (PV) module conversion efficiency to 18.6% aperture efficiency for a full-size module, as measured and certified by the US Department of Energy's National Renewable Energy Laboratory (NREL).
 
The firm says that, for the first time ever, a module has been demonstrated that is more efficient than the best multi-crystalline module recorded. The 18.6% aperture-area efficiency corresponds to a full-area conversion efficiency of 18.2%, beating the best recorded multi-crystalline silicon PERC (passivated emitter rear contact) module with an approximate full-area efficiency of 17.7% (based on 19.1% aperture efficiency and published module area data).
 
The modules have also passed the industry's most rigorous multi-stress testing protocols such including Atlas 25+, IEC Long Term Sequential and Thresher Tests.
