The short-circuit current of a Silicon solar cell is proportional to the solar radiation. The Si-12TC sensors use a monocrystalline solar cell that is operated in short-circuit mode using a low-impedance resistor. All sensors have active temperature compensation. The solar cell is embedded in ethylene vinyl acetate (EVA) between glass and a Tedlar film and integrated into a housing made of anodized aluminum. The structure of the Si sensor therefore corresponds to that of a PV module. A UV-resistant cable is used to make the electrical connection. In addition to measuring radiation, the Si-12TC-T sensors enable measurement of the solar cell temperature by means of a temperature sensor directly laminated on the cell.
