摘要
选取单晶硅、多晶硅和模拟非晶硅封装太阳电池为研究对象,研究了偏置光的辐照度和光谱分布等偏光光谱特性对太阳电池光谱响应的影响。太阳电池的光谱响应与偏置光有关,随着偏置光辐照度增大,长波段范围内的光谱响应增大,太阳电池短路电流呈线性增大。偏置光的光谱分布对太阳电池的光谱响应也有影响,光谱失配度越大,光谱响应的差异越大。为了提高太阳电池光谱响应测量的准确性,偏置光的辐照度和光谱分布应该尽量接近IEC标准。
Using monocrystalline silicon, multicrystalline silicon and simulated amorphous silicon solar cells as research objects, we study the influences of bias spectral characteristics such as irradiance and spectral distribution on the spectral response （SR） of solar ceils. The SR of solar cells is related to the bias light. The SR at long wavelength region increases and the short-circuit current of solar cell increases linearly with the increase of irradiance of bias light. The spectral distribution of bias light also has influence on the SR of solar cell. Large spectral mismatch degree induces large difference in SR measurement. Therefore, the irradiance and spectral distribution of bias light should be as close as possible to the IEC standard in order to improve the accuracy of SR measurement of solar cells.
