硅电池辐照测量仪光谱失配修订研究

摘要

设计了两款利用硅太阳电池作为传感器的高精度辐照测量仪,包括水平总辐照测量仪和直射散射测量仪;针对硅太阳电池实际光谱失配对辐照度计算影响的问题,提出了一种光谱采集处理的方法,通过实验采集晴天、多云、阴天、雨天的光谱数据,将实际光谱曲线计算的光生电流与AM1.5光谱下计算的光生电流进行比对修正得光谱对辐照度的影响因子,确定修正系数.%Two silicon cell pyranometers with high precision were designed,including horizontal pyranometer and direct-diffuse pyranometer.For the influence of the realistic spectral mismatch of silicon cell pyranometer,a method of spectral collection and processing was proposed.The photocurrent induced by the curve of realistic spectral experiments in clear,cloudy,overcast and rainy day was compared with the photocurrent calculated at AM1.5 to acquire the factor and correction coefficient.
