Based on the onediode equivalent circuit cell model,a mathematical model of triplejunction GaInP/GaInAs/Ge solar cells is established,and the calculation method of solar cell series resistance is proposed.The series resistance of the triplejunction solar cell at different temperatures(298,318,338,358 K) and different concentrating ratio (200,300,500,1 000 X) was calculated.The effect of series resistance on the performance of solar cells under different temperatures and different concentration ratio were analyzed.The results show that when the concentration ratio is 200X,the filling factor of the triple junction solar cell is reduced from 86.43% of 298 K to 83.60% of 358 K,and the conversion efficiency is reduced from 37.53% of 298 K to 33.70% of 358 K.At 298 K,the fill factor of the triple junction solar cell is decreased from 86.43% of 200X to 80.34% of 1 000X,and the conversion efficiency first is increased from 37.53% of 200X to 38.25% of 500X,and then decreased to 37.43% of 1 000X.
