摘　　要：为长期监测光伏电站中太阳辐射强度,设计了一种户外用硅基太阳总辐射计。采用同种技术类型硅太阳电池作为传感器,并以光伏组件制作工艺来封装硅太阳电池;采用测温热敏电阻测试硅电池的工作温度,为辐照度测量值增加温度修正;采用合适的取样电阻串接于硅电池正负极两端,使硅太阳电池近似工作于短路电流状态。最后在户外自然光下与标准硅太阳电池进行辐照度对比测试,最大误差为1.2%,最小误差为0.2%,平均误差为0.4%。A silicon-based total solar radiometer for outdoor use is designed.The silicon solar cells of the same technology type are used as sensors, and the silicon solar cells are encapsulated by photovoltaic module manufacturing process. The temperature measuring thermistor is used to measure the working temperature of the silicon cell, and the temperature correction is added to the irradiance measurement value. In addition, a suitable sampling resistor is connected in series to the positive and negative terminals of the silicon solar cell to make the silicon solar cell work approximately in the short-circuit current. Finally, the irradiance contrast test is conducted with standard silicon solar cells under outdoor natural light. The maximum error is 1.2%, the minimum error is 0.2%, and the average error is 0.4%.
