Description
| - Dual-junction solar cells have the potential for higher conversion efficiencies than single junctions, thanks to a better utilization of the solar spectrum. However, their optimization is more complex because the monolithic interconnection makes the individual subcell electrical measurement difficult or impossible. This study presents a new technique to measure the open-circuit voltage V-OC of each individual subcell of a dual-junction device with a method that circumvents the need for completely selective illumination. The method is based on the description of the total device V-OC 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 V-OC of the individual subcells at 1-sun illumination.
