5.1x00a0;The calculated error in the photovoltaic device current determined from the spectral mismatch parameter can be used to determine if a measurement will be within specified limits before the actual measurement is performed.

5.2x00a0;The spectral mismatch parameter also provides a means of correcting the error in the measured device current due to spectral mismatch.

5.2.1x00a0;The spectral mismatch parameter is formulated as the fractional error in the short-circuit current due to spectral differences.4^,5

5.2.2x00a0;Error due to spectral mismatch can be corrected by dividing the measured photovoltaic cell current by M , a procedure used in Test Methods E948 and E1036.

1.1x00a0;This test method covers a procedure for the determination of a spectral mismatch parameter used in performance testing of photovoltaic devices.

1.2x00a0;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 to which the photovoltaic reference cell was calibrated. Examples of reference spectral irradiance distributions are Tables E490 or G173.

1.3x00a0;The spectral mismatch parameter can be used to correct photovoltaic performance data for spectral mismatch error.

1.4x00a0;This test method is intended for use with linear photovoltaic devices.

1.5x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6x00a0;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.
