为了分析太阳光谱的直接光谱分布对聚光光伏（CPV）系统室外性能的影响，需要一个直接光谱分布指数。平均光子能量（APE），即太阳直射光谱中光子的平均能量，是这些指标之一。在这方面的贡献，APE的唯一性直接太阳光谱分布的统计分析，以确保APE值唯一地产生的形状的直接太阳辐射光谱。结果表明，在不同的APE值下，太阳正射直谱是唯一的，其标准偏差很小。利用不同APE值下的直接光谱辐照度，计算了CPV系统中InGaP/InGaAs/Ge三结太阳电池的短路电流密度。结果表明，APE是一个有用的指标来描述的直接光谱分布，以评估的CPV系统的室外性能。
To analyze the impact of a direct spectral distribution of the solar spectrum on the outdoor performance of concentrator photovoltaic (CPV) systems, an index for the direct spectral distribution is needed. Average photon energy (APE), the average energy of a photon in the direct solar spectrum, is one of these indexes. In this contribution, the uniqueness of APE to the direct solar spectral distribution is statistically analyzed to assure that an APE value uniquely yields the shape of a direct solar radiation spectrum. The results have exhibited the uniqueness of the direct normal solar spectrum with each APE value, in which the standard deviations are quite small. Short-circuit current density of the InGaP/InGaAs/Ge triple-junction solar cell in the CPV system is additionally calculated using the direct spectral irradiance with different APE values. It is revealed that APE is a useful index to describe the direct spectral distribution to evaluate the outdoor performance of the CPV systems.
