The work here is in the solar realm known as thermophotovoltaics, where PV cells are coupled with heat sources,
but they say theye made a breakthrough that could take thermophotovoltaics far beyond where it gone before. mit thermophotovoltaics MIT nanophotonic solar thermophotovoltaic device, with an array of multialled carbon nanotubes as the absorber, a oneimensional silicon/silicon dioxide photonic crystal as the emitter
and they point to advantages that thermophotovoltaics could have over PV: The new solar thermophotovoltaic systems, they say,
could provide efficiency because of their broadband absorption of sunlight; scalability and compactness, because they are based on existing chip-manufacturing technology;
By the way, this isn the first foray into thermophotovoltaics at MIT that wee reported on. See our earlier story on a technique that one expert said could lead to miniature power supplies and lighter portable electronics e
which can be absorbed by solar cells to make electricity a technology known as thermophotovoltaics. Unlike earlier prototypes that fell apart before temperatures reached 2200 degrees Fahrenheit (1200 degrees Celsius) the new thermal emitter remains stable at temperatures as high as 2500 F
Instead of sending sunlight directly to the solar cell thermophotovoltaic systems have an intermediate component that consists of two parts:
which is quite remarkable. o far thermophotovoltaic systems have achieved only an efficiency level of about 8 percent Braun notes.
could help advance thermophotovoltaics as well other areas of research including energy harvesting from waste heat high-temperature catalysis
is established well. opefully these results will motivate the thermophotovoltaics community to take another look at ceramics
The material works as part of a solar-thermophotovoltaic (STPV) device: The sunlight s energy is converted first to heat
In this paper the authors demonstrated in a system designed to withstand high temperatures the engineering of the optical properties of a potential solar thermophotovoltaic absorber to match the sun s spectrum.
Aydin said this design can also be used in applications for photothermal therapy thermophotovoltaics heat-assisted magnetic recording thermal emission and solar-steam generation.
