Solar Efficiency Records Broken for Thin-film Technology: Getting nearer to Silicon PV.

That’s right, not one, but two thin-film solar photovoltaic (PV) technologies broke efficiency records last week. Both technologies put their thin-film PV within much closer range of silicon-based PV, which comprise the overwhelming majority of installed solar power today. Sinc
A world record for cadmium-telluride (CdTe) PV cells, converting 20.4 percent of the sun’s energy into electricity. The cell was built by First Solar in USA. It is certified by NREL. It is still less than silicon PV, cells that convert 24.7 percent of the sun’s energy into electricity, but it’s generally much less expensive to produce thin-film PV since it can use less expensive components and processes than most silicon technology requires.
Stion another USA company announced that it produced a 23.2 efficient copper indium gallium (di)selenide (CIGS)-based thin-film cell. However it is not yet certified by NREL.
