论文摘要
由于温度和光谱变异性的综合作用，在标准测试条件下，现场光伏模块的平均效率通常低于实验室中在实验室中测得的效率，从而影响了电厂项目的持续性。我们报告校正因子，以说明硅模块产生能量的频谱效应，具体取决于位置和收集器几何形状。在高辐照度的位置，如果忽略了光谱敏感性效应，则追踪器的能量产量优势被低估了0.4％。我们发现最有利于跟踪的位置与最有利于多峰的位置之间的相关性。随着光伏市场的增长量增长，这些看似很小的影响预计在未来几十年中具有相当于数万美元的经济影响，远远超过了所需的研究工作的成本。
The time averaged efficiency of photovoltaic modules in the field is generally lower than the efficiency measured in the laboratory under standard testing conditions due to the combined effects of temperature and spectral variability, affecting the bankability of power plant projects. We report correction factors to account for spectral effects ranging from -2% to 1.3% of the produced energy for silicon modules depending on location and collector geometry. In high irradiance locations, the energy yield advantage of trackers is underestimated by 0.4% if spectral sensitivity effects are neglected. We find a correlation between the locations most favourable for tracking, and those most favourable for multijunctions. As the photovoltaic market grows to a multi-terawatt size, these seemingly small effects are expected to have an economic impact equivalent to tens of billions of dollars in the next few decades, far out-weighting the cost of the required research effort.
