Based on the scientific research and productions actual needs, we designed a solar cell test system based on MCU, this system primarily includes two sections,that is data acquisition and data processing and results displaying. 1. According to the test principle of the solar cell and the related knowledge about electronic circuit, we have choosed suitable electronic components to design a hardware circuit, which can complete the task of data acquisition, this hardware circuit includes temperature data acquisition unit ，light intensity signal acquisition unit, vokage and current signal acquisition unit, analogue to digital conversion unit and serial communication unit, and so on. 2. We used MCU C programming language to compile sofeware program coordinated with the data acquisition hardware circuit, controlling hardware circuit to complete the task of data acquisition, and the serial communicating between data acquisition section and personal computer。 Key words : solar cell；MCU；data acquisition 目 录 第1章 绪论 1 1.1设计题目及背景 1 1.1.1设计题目 1 1.1.2 设计背景 1 1.2 研究目的及意义 4 第2章 设计原理及要求 5 2.1 太阳能电池的工作原理 5 2.2 太阳能电池的分类 6 2.3 太阳能电池的等效电路 7 2.4 太阳能电池的伏安特性
