Major Advance in New Solar Cell Materials Achieved by BGU Researchers and Colleagues from Singapore and Switzerland (Ben-Gurion University of the Negev)

(Source: Ben-Gurion University of the Negev) ​ A tri-national team (Singapore-Israel-Switzerland) that includes two BGU professors has reported a major advance in the physics of perovskite solar cells - a new class of inorganic-organic hybrid materials that is spawning a revolution in photovoltaic technology. 'Perovskite' refers to a specific type of crystal structure, originally identified by the 19th century Russian mineralogist L.A. Perovski, but which remained unrecognized as a promising solar cell material until 2009. In the most rapid set of advances in the history of photovoltaic technology, cell efficiencies rose from 3% for the initial devices,...
