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

Improving energy conversion efficiency in power electronics is vital for a sustainable society, with wide-bandgap semiconductors like GaN and SiC power devices offering advantages due to their ...

A peer-reviewed field study has demonstrated that software-driven controls can allow a standard 120-volt heat-pump water heater to deliver reliable hot water without backup resistance elements, ...

Flexible solar cells have many potential applications in aerospace and flexible electronics, but low energy conversion efficiency has limited their practical use. A new manufacturing method has ...

New data shows nearly 70 GW of new solar generating capacity is scheduled to come online across 2026 and 2027. That’s nearly a 49% jump over current operating capacity, and a huge boost for our clean ...

Now, Takahito Iida at the University of Osaka has proposed a new energy-harvesting technology that uses gyroscopic flywheel system that can be tuned to absorb energy efficiently over a broad range of ...

Metal-halide perovskite solar cells are attractive for next-generation photovoltaics due to their low fabrication cost and rapidly rising efficiencies. However, exposure to light and oxygen generates ...

In a conventional solar cell, the energy of an absorbed photon in excess of the band gap is rapidly lost as heat, and this is one of the main reasons that the theoretical efficiency is limited to ~33% ...

What if the future of solar energy wasn’t just brighter but fundamentally redefined? Imagine a world where solar panels are not only more efficient but also cheaper, more durable, and adaptable to ...
