1.1 These test methods cover calibration and characterization of non-primary terrestrial photovoltaic reference cells to a desired reference spectral irradiance distribution. 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 a photovoltaic device.
1.2 Non-primary reference cells are calibrated indoors using simulated sunlight or outdoors in natural sunlight by reference to a previously calibrated reference cell, which is referred to as the calibration source device.
1.2.1 The non-primary calibration will be with respect to the same reference spectral irradiance distribution as that of the calibration source device.
1.2.2 The calibration source device may be a primary reference cell calibrated in accordance with Test Method , or a non-primary reference cell calibrated in accordance with these test methods.
1.2.3 For the special case in which the calibration source device is a primary reference cell, the resulting non-primary reference cell is also referred to as a secondary reference cell.
1.3 Non-primary reference cells calibrated according to these test methods will have the same radiometric traceability as that of the calibration source device. Therefore, if the calibration source device is traceable to the World Radiometric Reference (WRR, see Test Method ), the resulting secondary reference cell will also be traceable to the WRR.
1.4 These test methods apply only to the calibration of a photovoltaic cell that demonstrates a linear short-circuit current versus irradiance characteristic over its intended range of use, as defined in Test Method .
1.5 These test methods apply only to the calibration of a photovoltaic cell that has been fabricated using a single photovoltaic junction.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
