The method is based on the description of the total device VOC as a function of two independent variables determined by two distinct illumination spectra. Without completely selective illumination, one can measure only a limited range of this function; however, an unambiguous extension gives values corresponding to the conditions of ideal selectivity, which correspond in turn to the VOC of the individual sub-cells at 1 sun illumination. This method does not rely on any specific electrical or optical model of solar cell. Method is successfully tested with a simple measurement set-up based on commercially available luminescence diodes and voltmeters in combination with specially prepared three terminal dual-junction thin-film silicon solar cells.
