| 摘 要： | 通过实验比较了砷化镓量子阱太阳能电池与不含量子阱结构的普通砷化镓太阳能电池的外量子效率. 结果表明，量子阱太阳能电池吸收光子的波长从870nm 扩展到了1000nm. 当波长小于680nm时，量子阱太阳能电池的外量子效率低于普通太阳能电池；而当波长大于于680nm时，量子阱太阳能电池的外量子效率高于普通太阳能电池. 对这个现象给出了解释，并对用量子阱太阳能电池代替三结电池的中间子电池的可能性进行了讨论.

| Abstract: | The external quantum efficiency of quantum well solar cells (QWSCs) is compared with the control cells without multi-quantum wells.The QWSCs extend the absorption spectrum from 870 to 1000nm.When the wavelength is below 680nm,the external quantum efficiency of the QWSCs is lower than that of the control cells,but when the wavelength is above 680nm,the external quantum efficiency of the QWSCs is higher than that of the control cells.The possible reasons for this phenomenon are discussed.Basing on the experimental data,the possibility of substituting the middle cells of conventional triple-junction solar cells with the QWSCs to improve their performance is also discussed. |
