The technology for controlling light absorption at selected wavelengths in nanostructures has garnered much attention in recent years; however, dynamically tuning absorption wavelengths without also changing the geometry ...
New all-inorganic perovskite solar cells tackle three key challenges in solar cell technology: efficiency, stability, and cost.
The next generation of energy-efficient power electronics, high-frequency communication systems, and solid-state lighting rely on materials known as wide bandgap semiconductors. Circuits based on these materials can operate ...
Single crystal tin selenide (SnSe) is a semiconductor and an ideal thermoelectric material; it can directly convert waste heat to electrical energy or be used for cooling. When a group of researchers from Case Western Reserve ...
Energy sustainability represents one of the grand challenges facing modern society, and thin-film solar photovoltaics provide one of the best opportunities for rapidly expanding renewable energy use. Photovoltaics (PV) using ...
The thinner the silicon crystal, the better. Indeed, thinner crystals provide better ways to manipulate the trajectories of very high-energy ions in particle accelerators. Further applications include materials analysis, ...
A new particle detector design proposed at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) could greatly broaden the search for dark matter—which makes up 85 percent of the total mass ...
Semiconductors, a class of materials that can function as both electrical conductor and insulator depending on the circumstances, are fundamental to modern electronics. Silicon is the most widely used semiconductor, but in ...
Silicon has long been the go-to material in the world of microelectronics and semiconductor technology. But silicon still faces limitations, particularly with scalability for power applications. Pushing semiconductor technology ...
Solar cells can't stand the heat. Photovoltaics lose some energy as heat in converting sunlight to electricity. The reverse holds true for lights made with light-emitting diodes (LED), which convert electricity into light. ...
