1.1This test method provides a procedure for the determination of a spectral mismatch parameter used in performance testing of photovoltaic devices.

1.2The spectral mismatch parameter is a measure of the error introduced in the testing of a photovoltaic device that is caused by the photovoltaic device under test and the photovoltaic reference cell having non-identical quantum efficiencies, as well as mismatch between the test light source and the reference spectral irradiance distribution to which the photovoltaic reference cell was calibrated.

1.2.1Examples of reference spectral irradiance distributions are Tables E490 or G173.

1.3The spectral mismatch parameter can be used to correct photovoltaic performance data for spectral mismatch error.

1.4Temperature-dependent quantum efficiencies are used to quantify the effects of temperature differences between test conditions and reporting conditions.

1.5This test method is intended for use with linear photovoltaic devices in which short-circuit is directly proportional to incident irradiance.

1.6The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7This 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.

1.8This 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.
