Silicon Irradiance Sensor with spectral Adaption

Stop of production in 2017

For the monitoring of amorphous silicon photovoltaic systems we offer silicon solar radiation sensors (all models in the same housing designs available for Si) as spectrally adapted reference cells. Just like the standard models, these specially adapted sensors are equipped with a monocrystalline (mSi) solar cell as the sensor element. In order to compensate for the significant differences in spectral sensitivity between mSi and aSi material, the adapted sensors are encapsulated in a special filter glass. This composite material is able to achieve the spectral sensitivity of aSi material to an outstanding degree.
This process results in an excellent combination of the advantages of mSi material (very good linearity and stability) with the spectral behaviour of aSi photovoltaic modules, offering optimally tuned reference cells for monitoring aSi photovoltaic systems.
