ASTM E927-2019陆地光电试验用阳光模拟装置的规格Standard Classification for Solar Simulators for Electrical Performance Testing of Photovoltaic Devices

1.1 This classification provides means for assessing the suitability of solar simulators for indoor electrical performance testing of photovoltaic cells and modules, that is, for measurement current-voltage curves under artificial illumination.

1.2 Solar simulators are classified according to their ability to reproduce a reference spectral irradiance distribution (see Tables G138 and E490), the uniformity of total irradiance across the test plane, and the stability of total irradiance over time.

1.3 A solar simulator usually consists of three major components: (1) light source(s) and associated power supplies; (2) optics and filters required to modify the irradiance at the test plane; and (3) controls to operate the simulator, including irradiance adjustment.

1.4 This classification is applicable to both pulsed and steady-state solar simulators.

1.5 Many solar simulators also include integral data acquisition systems for photovoltaic performance testing; these data acquisition systems are outside of the scope of this classification.
