This test method covers the determination of the electrical performance of a photovoltaic cell under simulated sunlight by means of a calibrated reference cell procedure. Electrical performance measurements are reported with respect to a select set of standard reporting conditions (SRC) (see ) or to user-specified conditions. The SRC or user-specified conditions include the cell temperature, the total irradiance, and the reference spectral irradiance distribution. This test method is applicable only to photovoltaic cells with a linear response over the range of interest. The cell parameters determined by this test method apply only at the time of test, and imply no past or future performance level. 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.
