Power/Performance Bits: Feb. 4


Lead halide perovskites Paving the way to the design of photovoltaic converters with improved efficiency, researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) said they have uncovered the mechanism by which solar cells based on lead iodide perovskite light-absorbing semiconductor transfer electrons along their surface. Photovoltaic systems based on lead halide perovskite are a n... » read more

Power/Performance Bits: Sept. 17


Harvesting energy from light In a finding they believe could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications, researchers from the University of Pennsylvania and Duke University have demonstrated a new mechanism for extracting energy from light. They said the process is much more efficient than conven... » read more
