ASTM E 1039 : 1999

CONTAINED IN VOL. 12.02, 2001 Specifies procedure for calibration and characterization of primary terrestrial, silicon photovoltaic reference cells to the global reference spectral irradiance distribution specified by Tables E 892. Recommended physical requirements are outlined in E 1040. Reference cells are mainly used to determine electrical performance of a photovoltaic device. Calibration takes place outdoors in natural sunlight by reference to a pyranometer used for measuring global irradiance.

1.1 This test method is intended to be used for calibration and characterization of primary terrestrial, silicon photovoltaic reference cells to the global reference spectral irradiance distribution defined by Tables E892. The recommended physical requirements for these reference cells are described in Specification E1040. Reference cells are principally used in the determination of the electrical performance of a photovoltaic device.

1.2 Primary global reference cells are calibrated outdoors in natural sunlight by reference to a pyranometer that is used to measure the global irradiance.

1.3 This test method applies only to the calibration of a photovoltaic cell which demonstrates a linear short-circuit current versus irradiance characteristic over its intended range of use, as defined in Test Method E1143.

1.4 This test method applies only to the calibration of single- or poly-crystalline silicon reference cells that have been fabricated with a single photovoltaic junction.

1.5 There is no similar or equivalent ISO standard.

1.6 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.
