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.
Solar Thermophotovoltaics (STPVs) are solar driven heat engines which extract electrical power from thermal radiation. The overall goal is to absorb and convert the broadband solar radiation spectrum into a narrowband thermal emission spectrum tuned to the spectral response of a photovoltaic cell (PV) .
Fig. 1. (A) Schematic diagram of a thermophotovoltaic (TPV) device, where the radiator is made of a high temperature resistant material, and the cell is made of a p-n junction diode. Heat is added to the radiator from an external source, and a cooling loop keep the cell at near room temperature.
Photovoltaic (PV) panels convert a portion of the incident solar radiation into electrical energy and the remaining energy (>70 %) is mostly converted into thermal energy. This thermal energy is trapped within the panel which, in turn, increases the panel temperature and deteriorates the power output as well as electrical efficiency.
Understanding these effects is crucial for optimizing the efficiency and longevity of photovoltaic systems. Temperature exerts a noteworthy influence on solar cell efficiency, generally causing a decline as temperatures rise. This decline is chiefly attributed to two primary factors.
