1.1 These test methods provide special techniques needed to determine the electrical performance and spectral response of two-terminal, multijunction photovoltaic (PV) devices, both cell and modules.

1.2 These test methods are modifications and extensions of the procedures for single-junction devices defined by Test Methods E 948, E 1021, and E 1036.

1.3 These test methods do not include temperature and irradiance corrections for spectral response and current-voltage (I-V) measurements. Procedures for such corrections are available in Test Methods E 948, E 1021, and E 1036.

1.4 These test methods apply only to nonconcentrator terrestrial multijunction photovoltaic cells and modules.

1.5 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.
