A brief overview of some of the important aspects of performance measurement and characterization of solar cells has been presented. The intent has been to illustrate some of the ways in which the reliable predictions of cell performance in the varied environment of outer space can be made. The techniques touched on here will necessarily need to be supplemented as new cell types are developed to the point where space power designers begin to seriously consider their use. These newer cell types are expected to be made of more exotic materials, will be more efficient, possibly made of very thin films and most certainly the cell designs will incorporate multiple junctions. New fixture systems will have to be developed to match the new cell contact systems. The simple measurement of I-V curves of cells with multiple bandgaps present special problems in cases where one of the junctions may be very sensitive to that part of the simulator spectrum where it substantially deviates from the true solar spectrum. It is very likely that better solar simulators may have to be developed in order to measure these cells with any degree of accuracy, and a host of new standard solar cells will have to be produced, calibrated, and maintained. Spectral response measurements will be a special problem too.
