摘要

发光耦合（LC）效应是通过改善子电池之间的电流失配进一步提高多结太阳能电池效率的策略之一。本研究采用激光束诱导电流映射表征方法研究了 III-V 族化合物 InGaP/GaAs/InGaAs 倒置变质三结太阳能电池（IMM-3JSC）中的 LC 效应。结果表明，在 7 个太阳辐照度下，IMM-3J 样品底部子电池中的低电压效应很强，低电压产率约为 0.13。此外，通过有效地均化低电压效应，IMM-3JSCs 的底部子电池有可能在 10 太阳辐照度下获得 ∼0.6 mA/cm2 的电流密度。

Luminescent coupling effect in InGaP/GaAs/InGaAs inverted metamorphic triple-junction solar cell

The luminescent coupling (LC) effect is one of the strategies for further boosting the efficiency of multijunction solar cells by improving the current mismatch among subcells. This work examined the LC effect in III–V compound InGaP/GaAs/InGaAs inverted metamorphic triple-junction solar cell (IMM-3JSC) by the laser beam-induced current mapping characterization method. A strong LC effect in the bottom subcell of the IMM-3J sample was demonstrated with an LC yield of around 0.13 under 7 suns irradiance. In addition, by effectively homogenizing the LC effect, the bottom subcell of IMM-3JSCs may potentially gain a current density of ∼0.6 mA/cm2 at 10 suns irradiance.
