Calibration Cells and Power Meters

The Solar Reference Cell consist of a 20 x 20 mm monocrystalline silicon Photovoltaic Cell encased in a 92 x 70 x 16 mm metal enclosure with a protective quartz window and a temperature sensor.
The temperature sensor is a 100 ohm platinum Resistance Temperature Detector (RTD).

The Solar Reference Cells come with an ISO/IEC 17025 accredited certificate of calibration and compatible set of connecting cables.
The certificate includes:
Isc, Imax, Voc, Vmax, Pmax, Spectral Correction, Fill Factor, Area and Efficiency.
Measurements are made in accordance with ASTM E948 and E1021, traceable to NIST and NREL.

Note - the SC-LT-Q will be replaced with SOL-REF-Q-E devices when all SC-LT-Q products are depleted. These products are functionally the same but have different cable interfaces at the device. Sciencetech will provide SOL-REF-Q-E devices for any purchases of SC-LT-Q devices made after their inventory has been depleted. SC-LT-Q devices will continue to be supported by Sciecnetech.

This product consists of the Sciencetech SOL-METER and our SSIVT-REF sun calibrated reference detector. The SOL-METER is a digital meter for use with solar calibrated detectors such as detector models SSIVT-REF or SC-LT. The meter converts detector measurements to a Sun value. It has a handheld meter that is compact, has a sturdy design, and is appropriate for indoor or outdoor applications.
The Sciencetech Reference Detector, which is an integral part of solar simulator calibration and solar cell I-V characterization, consists of a calibrated solar detector made of silicon.
The Reference Detector comes with calibration data taken by Sciencetech, calibrating it to a NIST-certified solar cell, on an accompanying certificate. It reads solar simulator irradiance in "sun" units; one sun is equal to 1,000 W/m^2, at 25 degrees Celsius and Air Mass 1.5 Global.
This tool's primary use is the testing of photovoltaic cells under standard conditions.

The SCI-MO reference cell is a robust PCB-mounted solar cell with an active area of 22 × 7mm. The SCI-MO is intended to be used as a reference monitor for determining solar simulator sun level. These reference cells are calibrated for 1 Sun AM1.5G using a Sciencetech Class AAA (ASTM E927-19) solar simulator. Two calibration values (Isc) in mA/Sun and mV/Sun are provided. The SCI-MO is used as the reference cell in PTS-series instruments.

Readout options for the SCI-MO require accessories. They are:
Current (in mA): in no load mode, requires a source meter (such as in SSIVT-series current-voltage measurement systems) to read out.
Voltage (in mV): in loaded mode, requires a simple voltmeter/multimeter (such as MULTIMETER), or a source meter (such as in SSIVT-series current-voltage measurement systems) to read out.
Suns: in no load mode, requires SOL-METER to read out (using current, an integrated load resistor, and a pre-loaded calibration value to display Suns).

Readout accessories, such as SOL-METER, MULTIMETER, and SSIVT-series instruments are sold separately.

The reference cell can be switched into loaded or unloaded mode via a surface mounted switch on the top of the detector PCB. A calibration value is provided for each mode of operation.
A disconnectable 1.2m long cable assembly with 4 color coded banana plugs is provided with each device.

The SCI-MO reference cell is RoHS compliant.
