The Oriel^® 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.
