6 Frequently Asked Questions about “Classification standards for thermophotovoltaic cells”
What is thermophotovoltaics (TPV)?
Optica (2018), 5 (2), 213-218 CODEN: OPTIC8; ISSN: 2334-2536. (Optical Society of America) Thermophotovoltaics (TPV) is the process by which photons radiated from a thermal emitter are converted into elec. power via a photovoltaic cell.
What is thermophotovoltaic energy conversion?
Thermophotovoltaic (TPV) energy conversion is a direct conversion process from heat to electricity via photons. A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object.
What is a high-efficiency thermophotovoltaic (TPV) generator?
(Elsevier B.V.) The confluence of high-temp. (∼1600-3200 K) flameless combustion chambers and vertical-junction (VJ) photovoltaics creates the possibility of ultra-compact high-efficiency thermophotovoltaic (TPV) generators. The actively-cooled cells can be sited at the chamber's aperture without contaminating or damaging them.
What is the temperature coefficient of a photovoltaic cell?
However, due to the heat generated in the cell, its temperature can exceed 25 °C. Advantageously, a moderate temperature coefficient of the electrical power of (−0.309 ± 0.005)%/ °C is measured under 1-Sun illumination and it becomes much smaller, (−0.18 ± 0.01)%/ °C, in thermophotovoltaic conditions.
Can actively cooled TPV cells be located at a chamber's aperture?
The actively-cooled cells can be sited at the chamber's aperture without contaminating or damaging them. The flux d., however, is then well above values at which conventional TPV cells can operate efficiently due to the series resistance losses at photo-generated current densities of the order of tens to hundreds of A/cm2.
How efficient are Gainas thermophotovoltaic devices?
Here, we report the design, fabrication, and testing of large area (0.8 cm2), scalable, single-junction 0.75-eV GaInAs thermophotovoltaic devices reaching an efficiency of 38.8% ± 2.0% and an elec. power d. of 3.78 W/cm2 at an emitter temp. of 1,850°C.
