Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Scientists have developed a new model that explains how photon efficiency changes at higher wavelengths, paving the way for a more efficient quantum internet. Reading time 2 minutes Materials ...

Physics training taught Brian Gerke how to figure out anything; now he’s applying his skills to energy-efficiency research, helping to set national standards. Brian Gerke follows the second law of ...

Chemists at the University of California Riverside (UCR) have devised a way of increasing solar cell efficiency by as much as 30%. With current photovoltaic cells unable to surpass 33% due to the ...

There’s a annoying theoretical limit on the efficiency of solar cells that limits the amount of electricity they can create from sunlight. But now a team of MIT engineers has developed a system that ...

Solar power has long been constrained by a supposedly unbreakable ceiling on how much sunlight a panel can turn into electricity. That barrier is now cracking as a new class of solar materials pushes ...
