The Solar Reference Cells 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 a Certificate of Calibration and compatible set of connecting cables. The following parameters of the reference cell are certified: Isc, Imax, Voc, Vmax, Pmax, Area, Fill Factor and Efficiency. 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). A compatible cable set is also supplied with each Solar Reference Cell.
