WebHow a Thermopile Pyranometer Works The thermoelectric detection principle is used, whereby incoming radiation is almost completely absorbed by a horizontal blackened surface, over a very wide wavelength range. The resulting increase of temperature is measured via thermocouples connected in series or series-parallel to make a thermopile. WebTwo-dimensional thermopile arrays have been reported only by two groups. 92, 93 In both cases, a desire for low cost and manufacturability led to the use of polysilicon thermoelectric materials, which have relatively low thermoelectric figures of merit. Fote and co-workers 94, 95 have improved the performance of thermopile linear arrays by combining Bi-Te and …

WebThermopile Sensor Physics. Thermopile sensors are based on thermocouples. A thermocouple consists of two dissimilar metals connected in series. To detect radiation, one metal junction is typically blackened to absorb the radiation. The temperature rise of this junction with respect to another non-irradiated junction generates a voltage.
