Concentrated photovoltaic, now on your rooftop

The most efficient solar cells are those that convert incoming concentrated solar power via lenses, the sort you see on the International Space Station or  in the sun-soaked Middle East where  Shams 1, a 100 MW CSP plant – the largest in the world –  operates, powering 20,000 United Arab Emirates homes. Because of their complex nature, concentrated solar power arrays have

World Record Solar Cell With 44.7% Efficiency

The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for solar cell efficiency: 44.7% That means that 44.7% of all solar energy (from the Ultraviolet to the Infrared) is gathered and transformed into electricity. After going into research just three years ago, they managed to
