This paper focus on the influence of the width and distance of the grid lines for the fill factor (FF) and the short current (Isc) of the high-concentration multijunction solar cell, and the composition of the series resistance of the solar cell was studied. The results indicated. That, the fill factor (FF) increases with decreasing the distance of the grid lines, however in the same time, decreasing the Short-circuit Current Isc. so we should make a choice of the distance of the grid lines to maximize the product of Isc and FF, and the FF increases with decreasing the width of the grid lines. the efficiency of the triple junction (GaInP/GaAs/Ge) solar cell upto 39.58%, and the FF upto 88.1% under 1000 suns. ©, 2015, Science Press.
