trisense irradiance sensor
Genral Information
Mode of operation A silicon solar cell can be used as an irradiance sensor, because the short-circuit current is proportional to the irradiance. Our sensors are build out of a monocrystalline Si solar cell connected to a shunt. Due to the low resistance of the shunt the cell operates next to short-circuit. To minimize influences of temperature to the measuring signal all of our sensors have an active temperature compensation via a temperature sensor laminated to the back surface of the solar cell.
All sensors are calibrated in artificial sunlight against a reference cell calibrated at the Physikalisch-Technische Bundesanstalt (PTB, National Metrolo gy Institute of Germany).
