摘要
A quantum efficiency test controller (QETC) and related techniques for measuring quantum efficiency are described. The QETC performs one or more test iterations to obtain test results regarding quantum efficiency of a multijunction photovoltaic device (MPD) having a number N of photovoltaic junctions (N > 0), where the QETC is associated with N bias light sources. During a test iteration, the QETC activates a grating monochromator to emit a first test probe of monochromatic light at a first wavelength; and while the grating monochromator is emitting the first test probe, iterates through and activates each of the N bias light sources to emit a corresponding bias band of wavelengths of light. After performing the test iteration(s), the QETC generates an output that is based on the test results related to the quantum efficiency of the MPD.
