1.1 This test method describes the determination of a spectral mismatch parameter used in the testing of photovoltaic devices. The spectral mismatch parameter is a measure of the error, introduced in the testing of a photovoltaic device, caused by mismatch between the spectral responses of the photovoltaic device and the photovoltaic reference cell, as well as mismatch between the test light source and the reference spectral irradiance distribution, such as Standard Tables E490, E891, or E892, to which the photovoltaic reference cell was calibrated. Spectral mismatch, which is calculated using these four spectral quantities, is a quantitative measure of the error in the measured short-circuit current and can be used to correct photovoltaic performance data.

1.2 The spectral mismatch parameter is intended for use with linear photovoltaic devices.

1.3 This standard does not purport to address all of the safety problems, 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.
