Records in PV do not endure. The previous record -also held by Spectrolab -was 35.2% efficiency. Although one might think it likely that the latest result will last for some time, such is its significance, the company thinks that it can surpass 36.9% within the coming year or so.
Spectrolab says that the latest achievement is but one necessary step along the way to achieving one of the US Department of Energy's major PV initiative goals: to develop solar modules with a conversion efficiency of over 33% as targeted in the High Performance PV Project (www.nrel.gov/highperformancepv). The aim is to double sunlight-to-electricity conversion efficiencies in a project initiated by DOE in 2001. It is hoped that this will substantially increase the viability of PV for costcompetitive applications.
