German Fraunhofer Institute for Solar Energy Systems, Soitec,
CEA-Leti and the Helmholtz Center Berlin announced today that they have
achieved a new world record for the conversion of sunlight into
electricity using a new solar cell structure with four solar subcells.
Surpassing competition after only over three years of research, and
entering the roadmap at world class level, a new record efficiency of
44.7% was measured at a concentration of 297 suns. This indicates that
44.7% of the solar spectrum’s energy, from ultraviolet through to the
infrared, is converted into electrical energy. This is a major step
towards reducing further the costs of solar electricity and continues to
pave the way to the 50% efficiency roadmap.
