A description is given of an on-sun, high-concentration solar cell test facility. Because of predicted nonlinear properties of the cells fabricated, past methods of scaling short-circuit currents as a measurement of irradiance are not used. Instead, a water-cooled, blackbody calorimeter has been developed for use over a range of concentrations from 50 to 500 suns. The calorimeter is calibrated by means of an internal heater. The solar cell and calorimeter are mounted, in turn, behind a fixed aperture plate during measurements. Design and operational considerations are discussed, and system improvements are suggested.
