The resilience against non-idealities of hot-carrier multijunction solar cells (HCMJSCs) is assessed and compared with two references, namely a multijunction solar cell (MJSC) and a hot carrier solar cell (HCSC). We investigate the impact on the efficiency of three deviations from the ideal case: nonoptimal design, internal limitations, and nonstandard operation conditions. We show that the HCMJSC maintains a high efficiency even when materials with nonoptimal bandgaps are considered, broadening the range of candidate materials for its implementation. We also show that the requirement for hot carriers’ thermalization is much less stringent than with the standard HCSC architecture, allowing to surpass the best MJSC efficiency with currently achievable thermalization coefficients. Finally, we estimate the influence of nonstandard illumination by varying the AM spectrum and estimate numerically the yearly averaged efficiency of devices installed in two different locations. Preliminary results on temperature dependence are also presented.

热载流子多结太阳能电池：对非理想的敏感性和弹性

评估了热载流子多结太阳能电池 (HCMJSC) 对非理想的恢复能力，并与两个参考文献进行了比较，即多结太阳能电池 (MJSC) 和热载流子太阳能电池 (HCSC)。我们研究了与理想情况的三种偏差对效率的影响：非最优设计、内部限制和非标准操作条件。我们表明，即使考虑具有非最佳带隙的材料，HCMJSC 也能保持高效率，从而扩大了其实施的候选材料范围。我们还表明，与标准 HCSC 架构相比，对热载流子热化的要求要宽松得多，从而可以超越目前可实现的热化系数的最佳 MJSC 效率。最后，我们通过改变 AM 光谱来估计非标准照明的影响，并以数值方式估计安装在两个不同位置的设备的年平均效率。还介绍了温度依赖性的初步结果。
