论文摘要
钙钛矿/Si串联太阳能电池（P/SI TSC）的成功商业化需要对技术基准的A-Priori估算，以超过野外条件下的基于C-SI的技术。为此，通过详细的数值模拟和分析建模，我们在这里确定了离子迁移和生命周期降解的限制，直到P/Si TSC保持竞争力。我们的结果揭示了P/SI TSC的效率和温度系数的演变的独特缩放定律，这使我们能够预测限制的年度降解率。有趣的是，我们发现与2T细胞相比，4T细胞可能对离子迁移的不良影响更具影响。这些见解与材料/接口工程方法和基于物理的加速测试具有广泛的相关性，这些测试侧重于长期稳定性和模块可靠性。
Successful commercialization of Perovskite/Si tandem solar cells (P/Si TSCs) need a-priori estimation of technological benchmarks to outperform c-Si based technologies under field conditions. To this end, through detailed numerical simulations and analytical modeling, here we identify the limits of ion migration and lifetime degradation till which P/Si TSCs remain competitive. Our results unravel a unique scaling law for the evolution of the efficiency and the temperature coefficient of P/Si TSCs which allows us to anticipate the limiting annual degradation rates. Interestingly, we find that 4T cells are potentially more immune to the ill effects of ion migration as compared to 2T cells. These insights are of broad relevance for material/interface engineering approaches and physics based accelerated tests which are focused towards long term stability and module reliability.
