摘要

基于包晶石的串联太阳能电池（TSC）的稳定性是商业化之前需要克服的最后一项重大科学/技术挑战。了解流动离子对串联太阳能电池性能的影响是最大限度地减少降解的关键。本文介绍了一项综合研究，该研究利用与扫描速率相关的电流-电压（J-V）测量和漂移扩散模拟，对硅/过氧化物和全过氧化物 TSC 中的离子损耗进行了实验分析。研究结果表明，移动离子对串联电池的性能有显著影响，在稳态下，离子冻结功率转换效率从硅/过磷酸盐的 31% 和全过磷酸盐串联电池的 30% 降至 ≈28%。此外，在高扫描速度（400 s-1）下，离子会在硅/透闪石 TSC 中造成很大的滞后，并通过内场筛选显著影响这两种器件的性能下降。此外，对于全透闪石串联器件，以子电池为主的 J-V 特性分析表明，宽带隙子电池在老化过程中的离子损耗更为明显，这归因于其卤化物偏析倾向。这项工作为了解基于包晶的 TSC 中的离子损耗提供了宝贵的见解，有助于将与离子迁移相关的降解模式与其他降解机制区分开来，并指导采取有针对性的干预措施，以提高子电池的效率和稳定性。

Impact of Ion Migration on the Performance and Stability of Perovskite-Based Tandem Solar Cells

The stability of perovskite-based tandem solar cells (TSCs) is the last major scientific/technical challenge to be overcome before commercialization. Understanding the impact of mobile ions on the TSC performance is key to minimizing degradation. Here, a comprehensive study that combines an experimental analysis of ionic losses in Si/perovskite and all-perovskite TSCs using scan-rate-dependent current–voltage (J–V) measurements with drift-diffusion simulations is presented. The findings demonstrate that mobile ions have a significant influence on the tandem cell performance lowering the ion-freeze power conversion efficiency from >31% for Si/perovskite and >30% for all-perovskite tandems to ≈28% in steady-state. Moreover, the ions cause a substantial hysteresis in Si/perovskite TSCs at high scan speeds (400 s⁻¹), and significantly influence the performance degradation of both devices through internal field screening. Additionally, for all-perovskite tandems, subcell-dominated J–V characterization reveals more pronounced ionic losses in the wide-bandgap subcell during aging, which is attributed to its tendency for halide segregation. This work provides valuable insights into ionic losses in perovskite-based TSCs which helps to separate ion migration-related degradation modes from other degradation mechanisms and guides targeted interventions for enhanced subcell efficiency and stability.
