Time-resolved photoluminescence (TRPL) is a powerful tool to investigate charge carrier recombination processes in emissive materials. Perovskite materials are extremely promising for applications in solar cells; however, the interpretation of their TRPL is arduous due to the complicated nature of the recombination processes occurring in these materials. We present here the PErovskite cArrier Recombination Simulator (PEARS) web tool for effortlessly and quickly fitting TRPL of perovskite materials using advanced charge carrier recombination models, allowing for the extraction of recombination rate constants and trap state concentration. PEARS is flexible and can adapt to different situations, by ignoring recombination processes or fixing known parameters (e.g., the doping concentration). The tool is publicly available at https://pears-tool.herokuapp.com.
时间分辨光致发光（TRPL）是研究发光材料中电荷载流子复合过程的有力工具。钙钛矿材料在太阳能电池应用中极具前景；然而，由于这些材料中发生的复合过程非常复杂，因此对其 TRPL 的解释变得非常困难。我们在这里展示了 PErovskite cArrier Recombination Simulator（PEARS）网络工具，它可以使用先进的电荷载流子复合模型轻松快速地拟合钙钛矿材料的 TRPL，从而提取复合速率常数和陷阱态浓度。PEARS 非常灵活，可以根据不同的情况进行调整，例如忽略复合过程或固定已知参数（例如掺杂浓度）。该工具可在 https://pears-tool.herokuapp.com 上公开获取。
