ZSW hits 21.7 percent efficiency rate, setting the stage for reduced solar costs.
Utah, USA -- Everybody loves a new world record, even more so when that record hints at the possibility of enormous strides in solar power energy generation. According to information coming out of the Centre for Solar Energy and Hydrogen Research (ZSW) in Baden-Württemberg, Germany, scientists there have once again snatched up the title as creators of the highest performing thin-film PV cell in the world.
Smashing the previous record of 21 percent efficiency set by Swedish solar manufacturer Midsummer, ZSW says it has achieved 21.7 percent cell efficiency in laboratory conditions by way of a solar cell made of copper indium gallium selenide (or CIGS, for short). The new breakthrough kicks up the outperformance of CIGS against multicrystalline solar cells by 1.3 percent and sets the stage for further improvements that could drive the cost of CIGS technology down to competitive levels.
