SRI 6014 is a packaged photovoltaic (PV) cell that is calibrated to give the irradiance spectral responsivity and the short circuit current, I_sc, of a 20 mm PV cell under a well-defined reporting condition. The NIST PV cell calibration method is a primary method called the differential spectral responsivity technique, performed in irradiance mode, and has direct traceability to SI using other NIST calibrated specimens. The solar cell is mounted onto a small, printed circuit board and the board is fitted into the body of the housing with good thermal contact and a temperature sensor (thermocouple) for monitoring its temperature. It is also electrically wired in a 4-probe configuration and can be externally measured using a 4-probe cable (provided by NIST). This SRI has three versions. SRI  6014a is a silicon Calibrated Reference Photovoltaic Cell with a clear glass window, SRI 6014b is a silicon Calibrated Reference Photovoltaic Cell with a filtered glass window, and SRI 6014c is a gallium arsenide (GaAs) Calibrated Reference Photovoltaic cell with a clear glass window. The glass window is epoxied to the top of the housing to protect the cell, and if filtered, for altering the input spectrum reaching the solar cell. NIST currently offers 6 different reporting conditions as outlined in the specification document. The customer must choose the reference reporting condition. The most popular reporting conditions are based on the the air mass 1.5 global spectrum (AM1.5G) and the air mass 0 (AM0)
