Model 91150V Reference Cell and Meter
The Oriel® Reference Cells, which are 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 certification is accredited by NIST to the ISO-17025 standard and is traceable both to the National Renewable Energy Laboratory (NREL), and to the International System of Units (SI). 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. The window material choice is determined by the type cell being tested, to reduce spectral mismatch. 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.
