在理论上，光学薄光合系统将太阳辐射转换成化学能的最大效率被认为是光子收集色素的吸收光谱的函数。给出最大功率转换率的吸收带位置在全日光下接近700 nm，并且在较弱的光下在稍短的波长处。如果谱带太宽，则可获得的化学势降低。第二吸收带（或辅助色素）对电位的影响很小。
The maximum efficiency of an optically thin photosynthetic system in converting solar radiation into chemical energy is theoretically considered as a function of the absorption spectrum of the photon-collecting pigment. The absorption band position giving maximum rate of power conversion is close to 700 nm in full sunlight and at somewhat shorter wavelength in weaker light. The chemical potential obtainable is decreased if the band is too wide. The effect of a 2nd absorption band (or accessory pigment) on potential is rather small.
