Degradation mechanism of amorphous silicon solar cells is investigated during its operation, and a guideline for evaluation of the solar cell modules is proposed.In the first year, the system for measurement of the output characteristics of the modules was designed. The precise sunlight power meter, temperature and humidity sensor, and data logger for long term observation were installed, and monitoring of the solar power radiated to the modules was started. The solar power is an important parameter for evaluation of the efficiency of the modules.In the second year, the output characteristics of the module were monitored by using an air conditioner and a constant resistance as a load for the modules. The data of the voltage and current outputs for short, open, and loaded circuits were acquired periodically. The analysis of the data was performed on work sheets on a personal computer. It has been demonstrated that the evaluation system is useful for the long period monitoring of the characteristics of the modules in operation.

在运行过程中研究了无定形硅太阳能电池的降解机制，并提出了评估太阳能电池模块的指南。在第一年，设计了模块输出特征的测量系统。安装了长期观察的精确阳光功率计，温度和湿度传感器以及数据记录仪，并启动了对模块辐射的太阳能的监视。太阳能是评估模块效率的重要参数。第二年，使用空调和恒定电阻作为模块的负载来监测模块的输出特性。定期获取短，打开和加载电路的电压和电流输出的数据。数据分析是在个人计算机上的工作表上进行的。已经证明，评估系统可用于长期监视操作中的模块的特性。
