A Revolutionary Breakthrough In Photovoltaic TechnologyMay. 11, 2016
A tri-national team of scientists from Israel, Singapore and Switzerland has reported a major advance in the physics of perovskite solar cells – a new class of inorganic-organic hybrid materials that is creating a revolution in photovoltaic technology.
The researchers – among them Profs. Jeffrey M. Gordon and Eugene A. Katz, both from the Jacob Blaustein Institutes for Desert Research, Alexandre Yersin Department of Solar Energy and Environmental Physics at Ben-Gurion University of the Negev — used a combination of experiments that independently and expansively varied the intensity of incident light and cell temperature, toward elucidating the molecular mechanisms that permit these solar cells to exhibit surprisingly high voltage (more than 1.0 Volt per cell at ambient temperatures), while maintaining high current density and low internal resistive losses, which are essential for their superior performance.
