    Reference Solar Cell and Meter
    Reads calibrated sun irradiance and temperature
    Easily integrated with I-V Test Station
    The Reference Cell, which is an integral part of solar simulator
    calibration and solar cell I-V characterization, consists of a
    readout device and a 2 x 2 cm calibrated solar cell made of
    monocrystaline silicon. The cell is also equipped with a
    thermocouple assembled in accordance with IEC 60904-2. The
    Reference Cell comes with calibration data taken by NREL, on an
    accompanying certificate. It reads solar simulator irradiance in
    "sun" units; one sun is equal to 1000 W/m2 at 25 °C and Airmass
    1.5 Global Reference. This tool's primary use is the testing of
    photovoltaic cells under standard conditions. The Readout Meter
    includes two BNC connectors for analog outputs for the sun
    irradiance and the temperature.
