ENERGY CONVERSION AND TRANSFER ARRANGEMENT FOR THERMOPHOTOVOLTAIC DEVICES AND THERMOPHOTOVOLTAIC DEVICES COMPRISING SUCH

摘要

An energy conversion and transfer arrangement (10) including a spectral shaper (3) with an input surface (3.X) defining a flow-through heat transfer area (X) and an electro-magnetic radiation emitter (2) arranged within the flow-through heat transfer area (X) to allow for surface specific fuel combustion processes such as catalytic conversion which heat up the emitter to high temperatures. The electro-magnetic radiation emitter (2) is configured for emitting predominantly near-infrared radiation when exposed to high temperature. The spectral shaper (3) is configured as a band pass filter for a first, optimal spectral band of the radiation emitted by the electro-magnetic radiation emitter (2) when exposed to high temperature and/or as a reflector for further, non-optimal spectral band(s) of the radiation emitted by the electro-magnetic radiation emitter (2), so that the second, non-optimal spectral band radiation is recycled as radiation redirected towards the electro-magnetic radiation emitter (2).
