Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process produces per unit of fuel, physicists often compare how much of a substance’s ...

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 ...

Twelve photovoltaic storage systems with capacities of 5 kW or 10 kW were included in the comparison, among them several new products, all of which achieved efficiency class A. A new study – also ...

Achieving both a low operating temperature for photovoltaic (PV) and a high heat collection temperature for photothermal (PT) ...

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 ...

Maxwell has developed a perovskite/silicon heterojunction technology (HJT) tandem solar PV cell with a conversion efficiency of 32.5%.

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% ...
