High external quantum efficiency from double heterostructure InGaP/GaAs layers as selective emitters for thermophotonic systems
In thermophotovoltaics (TPV) an emitter is heated up to a high temperature and emits infrared light. Above bandgap photons can then be converted into power by photovoltaic cells at room temperature. One of the main disadvantages of TPV is the need for a highly perfect selective emitter or filter to achieve high conversion efficiency. Thermophotonics overcomes this through the use of a heated light-emitting diode as an extremely selective emitter. To achieve net conversion of heat to electricity...[Show more]
