摘　　要：忽略串联电阻,从太阳电池的I-V特性方程,数值分析并联电阻对I-V特性曲线的影响。正常情况下,并联电阻只影响太阳电池的填充因子,对开路电压和短流电流没有影响,但并联电阻极小时,能减小开路电压。并联电阻较小时,能显著地降低填充因子。从短路电流处的斜率,可以简便地计算太阳电池的并联电阻。Effect of shunt resistance on I-V characteristics curve of solar cell has by using numerical analysis of I-V equation in default of series resistance. Normal ance plays an important part on fill factor, short-circuit current. Small shunt resistance resistance can reduce open-circuit voltage at short-circuit current. been deduced shunt resist- but have no influence on open-circuit reduce fill factor significantly. Extreme It is simple to determine shunt resistance voltage and small shunt from slope
