1.1 This test method is intended for calibration and characterization of primary terrestrial photovoltaic reference cells to a desired reference spectral irradiance distribution, such as Tables . The recommended physical requirements for these reference cells are described in Specification . Reference cells are principally used in the determination of the electrical performance of photovoltaic devices.
1.2 Primary photovoltaic reference cells are calibrated in natural sunlight using the relative quantum efficiency of the cell, the relative spectral distribution of the sunlight, and a tabulated reference spectral irradiance distribution. Selection of the reference spectral irradiance distribution is left to the user.
1.3 This test method requires the use of a pyrheliometer that is calibrated according to Test Method , which requires the use of a pyrheliometer that is traceable to the World Radiometric Reference (WRR). Therefore, reference cells calibrated according to this test method are traceable to the WRR.
1.4 This test method is used to calibrate primary reference cells; Test Method may be used to calibrate secondary and non-primary reference cells (these terms are defined in Terminology ).
1.5 This test method applies only to the calibration of a photovoltaic cell that shows a linear dependence of its short-circuit current on irradiance over its intended range of use, as defined in Test Method .
1.6 This test method applies only to the calibration of a reference cell fabricated with a single photovoltaic junction.
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
