Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Perovskite solar cells have surged from laboratory curiosities to serious contenders against silicon in barely a decade, yet ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

There are roof shapes and ratios that maximize heat retainment and energy efficiency and, interestingly, ancient Italian architects and builders seemed to know it, too. While serving as a visiting ...

Working in tandem A perovskite-on-silicon tandem solar cell. (Courtesy: Oxford PV) Late in 2020, scientists in Germany and Lithuania announced a new milestone in so-called “tandem” solar cells – that ...

In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called ...

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 ...

The efficiency of perovskite LEDs (PeLEDs) is limited by electron traps that form due to structural defects. While defect passivation – the science of neutralizing these traps often with molecules – ...
