Solid-state Photon Enhanced Thermionic Emission for Solar Energy Conversion
Global climate imperatives require a worldwide shift away from greenhouse gasemitting activities such as fossil fuel combustion. Concentrated solar thermal installations are particularly appealing as they can store a fraction of their power in the form of heat to provide baseload power, yet current conversion efficiencies prevent them from reaching competitive market prices. One extremely promi...
متن کاملPhoton-enhanced thermionic emission for solar concentrator systems.
Solar-energy conversion usually takes one of two forms: the 'quantum' approach, which uses the large per-photon energy of solar radiation to excite electrons, as in photovoltaic cells, or the 'thermal' approach, which uses concentrated sunlight as a thermal-energy source to indirectly produce electricity using a heat engine. Here we present a new concept for solar electricity generation, photon...
متن کاملSolar energy conversion with photon-enhanced thermionic emission
Photon-enhanced thermionic emission (PETE) converts sunlight to electricity with the combined photonic and thermal excitation of charge carriers in a semiconductor, leading to electron emission over a vacuum gap. Theoretical analyses predict conversion efficiency that can match, or even exceed, the efficiency of traditional solar thermal and photovoltaic converters. Several materials have been ...
متن کاملPhoton Identification in ATLAS
This paper presents the results of research performed at CERN on photon identification. The shower shape variables used to identify photons are studied for the minimum bias data stream. Comparison to Monte Carlo data, performance study of efficiency in data and Monte Carlo are analyzed for the loose and tight photon identification selection. In addition some preliminary studies have been perfor...
متن کاملPhoton Emission
Heavy quark physics is one of the frontier areas in studies of the fundamental properties of matter. That is why a new generation of ee colliders (B-factories) has been designed. The CLEO-III , BELLE , and BABAR 3 experiments are running since 1999. Their main goal is the precise investigation of the CabibboKobayashi-Maskawa matrix and, first of all, CP-violation in the b-quark sector. To achie...
