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 admitted from the hot object. As TPV … Visa mer PV Typical photovoltaics work by creating a p–n junction near the front surface of a thin semiconductor material. When photons above the bandgap energy of the material hit atoms within the … Visa mer Efficiency The upper limit for efficiency in TPVs (and all systems that convert heat energy to work) is the Carnot efficiency, that of an ideal heat engine. This efficiency is given by: Visa mer Emitters Efficiency, temperature resistance and cost are the three major factors for choosing a TPV emitter. Efficiency is determined by energy absorbed relative to incoming radiation. High temperature operation is crucial … Visa mer RTGs Conventional radioisotope thermoelectric generators (RTGs) used to power spacecraft use a radioactive material whose radiation is … Visa mer Henry Kolm constructed an elementary TPV system at MIT in 1956. However, Pierre Aigrain is widely cited as the inventor based on lectures he gave at MIT between 1960–1961 which, unlike Kolm's system, led to research and development. In the 1980s, … Visa mer For black body emitters where photon recirculation is achieved via filters, Planck's law states that a black body emits light with a spectrum … Visa mer TPVs promise efficient and economically viable power systems for both military and commercial applications.
