光谱失配对标定太阳电池产生的影响分析

标准太阳电池的短路电流可用来确定太阳模拟器的总辐照度强度。选取单晶硅、多晶硅、非晶硅薄膜和染料敏化4种常见类型的太阳电池,分别进行光谱响应度测量。对光谱匹配分别为A、B、C级的太阳模拟器进行光谱辐照度分布测量。利用光谱失配计算公式,并结合标准AM1.5G太阳光谱辐照度分布数据,理论计算出由于光源间光谱不匹配以及电池间光谱响应度不匹配所产生的光谱失配因子,并对标定太阳电池产生的影响进行了分析。

Analysis of Spectral Mismatch's Impact on Solar Cell Calibration

Standard solar cell short circuit current can be used to determine the total irradiance intensity of the solar simulator. Four common types of solar cells were selected: monocrystalline,polycrystalline,a-Si thin film and dye-sensitized solar cell and the spctral response was measured. The spectral irradiance distribution of the solar simulators of class A,B and C on spectral match aspect was measured respectively. According to spectral mismatch calculation formula,combined with standard AM1.5G solar spectral irradiance distribution data, the spectral mismatch factor among light sources spectrum and cell spectral response was calculated, and the impact on solar cells calibration was analyzed.
