Calibrated Reference Cell, Meter, Quartz Window

The 91150V Reference Cell and Meter is an integral part of solar simulator calibration and solar cell I-V characterization. It consists of a readout device and a 2 x 2 cm calibrated solar cell made of monocrystalline silicon and a fused silica window. 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. 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.

Re-certification service of this system is proudly offered by our Newport Photovoltaic Calibration and Test Lab. Please contact a Newport Sales Engineer for more details.

Critical Tool for Testing PV Cells

The primary application of this system is to set the irradiance level of a solar simulator near to 1.000 Sun so that photovoltaic cells can be tested under standard reporting conditions.

Reference Cell Window Options

The reference cell consists of a 2x2 cm monocrystalline silicon photovoltaic cell with a choice of two windows. The KG5 heat absorbing window offers high transmission for visible wavelengths and absorb IR wavelengths. For a wider wavelength transmission range, a fused silica (quartz) window option is available. The KG1, KG2, and KG3 windows and respective traces are no longer available for standard ordering, and are referenced for legacy purposes only.  For customized solutions featuring these traces, please refer to our FSQ products in our heat absorbing glass shortpass filters product family.
