Product Description

Meteorology Application, Light intensity measurement for the car windows, Agriculture application, Solar radiation measurement, Physics and optical laboratories.

A silicon solar cell can be used as an irradiance sensor, because the short-circuit current is proportional to irradiance. Our sensors are built out of a monocrystalline solar cell connected to a shunt. Due to the low resistance of the shunt the cell operates next to short circuit.
The compensation is realized by using a specific temperature sensor laminated to the rear side of the solar cell.
