摘　　要：本文讨论了电阻测量的2种接线方式,以及用四线制测量代替传统的二线制测量的优点。通过在太阳能电池测试系统中的应用,不仅消除了系统内阻带来的误差,使得太阳电池测试仪能够精确地得到各个参数以及绘制出I-V曲线和P-V曲线,而且大大减小了电路板的体积,使得调试更方便可靠,节省了人力物力。This paper discussed two methods of resistance measurement, and the excellence of four-line The application of four-line measurement to solar cell tester not only eliminates the error made by the system, so as to get each parameters and protract I-V curves and P-V curves accurately, but also reduces the volume of circuit board greatly which makes the debug more convenient and reliable. At the same time, manpower and material resources are saved.
