1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born. The principle of ...
Typically, if you want to convert solar energy into electrical energy, you use either photovoltaic (PV) cells, or you use the sunlight to create steam to turn a turbine. Both of these methods are well ...
A Spanish-Italian research group has developed a solid-state thermal-to-electric energy converter based on hybrid thermionic-photovoltaics (TIPV) for different applications. It consists of a ...
Finding alternative optoelectronic mechanisms that overcome the limitations of conventional semiconductor devices is paramount for detecting and harvesting low-energy photons. A highly promising ...
