空气质量调节剂经常被用来表示太阳光谱对光伏组件电流的影响。现有的光伏组件性能模型假设一个单一的经验表达式，即空气质量的多项式，适用于所有地点和时间。本文通过在美国三个气候不同的地点用固定方向的模块测量的IV曲线估计了几个不同类型模块的气团调节剂。太阳光谱对光伏组件电流的影响有系统的变化，这种变化不能很好地近似于标准的空气质量修正多项式。
Air mass modifiers are frequently used to represent the effects of solar spectrum on PV module current. Existing PV module performance models assume a single empirical expression, a polynomial in air mass, for all locations and times. In this paper, air mass modifiers are estimated for several modules of different types from IV curves measured with the modules at fixed orientation in three climatically different locations around the United States. Systematic variation is found in the effect of solar spectrum on PV module current that is not well approximated by the standard air mass modifier polynomial.
