1.1 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.1.2 Electrical performance measurements are reported with respect to a select set of standard reporting conditions (SRC) (see ) or to user-specified conditions.1.2.1 The SRC or user-specified conditions include the cell temperature, the total irradiance, and the reference spectral irradiance distribution.
