摘　　要：采用LabVIEW软件平台搭建一套自动化Ⅰ-Ⅴ曲线测试系统,系统的数据采集部分由LabVIEW 8.5软件、VISA4.1库、Keithley 2000数字源表、低压电源和计算机等软、硬件所组成.对结构为ITO/PEDOT:PSS/P3HT:PCBM/Al的有机太阳能电池进行的Ⅰ-Ⅴ曲线测试,开路电压为0.608V,短路电流为8.25mA/cm2,填充因子为0.662,电池的转换效率为3.32%,其结果与CHI660电化学测量系统测量的结果相近,表明此系统具有可靠性、实时性和准确性等特点.A auto-testing system based on LabVIEW was designed for voltage-current characteristics, which was based on LabVIEW 8. 5 express, Visa 4. 1, Keithley 2000, low-voltage power supply and computer. It was applied to test the voltage-current characteristics of organic solar cells with the structure of ITO/PEDOT： PSS/P3HT： PCBM/A1, and its open circuit vihage was 0. 608 V, short circuit current was 8. 25 mA ·cm 2 fill factor was 0. 662, energy conversion efficiecy was＇ 3.32%, which was as much as the results measured by the CHI660 electrochemical measurement system. It was showed the system had reliable, real-timed and accurate properties.
