Abstract

In this paper, we present an empirical error correction procedure for efficiency measurements of series-connected, multijunction concentrator solar cells. The error arises from the use of unfiltered xenon flash solar simulators with excess infrared radiation (wavelengths > 900 nm) into lower-bandgap subcells, and always results in an artificial increase of the measured efficiency. The efficacy of the procedure is demonstrated by comparing unfiltered efficiency data against other data from a flash simulator in which the spectral irradiance was properly adjusted.
