AI 中文摘要
在钙钛矿太阳能电池中，移动离子与光激发电荷载流子之间的相互作用很复杂，近期研究表明移动离子对电池效率的影响取决于电池特性。本研究利用漂移扩散建模和因子分析，对601对钙钛矿太阳能电池（共1202个电池）在广泛的物理相关材料参数下进行模拟。每对器件中，一个电池含可自由移动的离子，另一个相同但无移动离子。通过该方法系统研究移动离子对电池性能的影响，解卷积关键电池参数的贡献，发现高效器件中移动离子对稳态性能影响小。
英文摘要
In perovskite solar cells, the interplay between mobile ions and photo-excited charge carriers is complex,with recent studies suggesting mobile ions can be either beneficial or detrimental to cell efficiency depending on the cell properties. In this study we use drift diffusion modelling and factorial analysis to simulate 601 pairs of perovskite solar cells (1202 total cells) across a broad range of physically relevant materials parameters. In each pair of devices, one cell contains mobile ions that can move freely. The second paired cell is identical but has no mobile ions. This approach allows us to systematically investigate the impact of mobile ions on cell performance. We deconvolve the contributions of key cell parameters including ion density, recombination rate and band offsets, for n-i-p and p-i-n devices with both organic and inorganic contact layers. Importantly, we find that in efficient devices, mobile ions have only a small impact on steady-state performance.
