钙钛矿材料稳定性数据集

钙钛矿太阳能电池作为新型的光伏技术，在近十多年得到迅速发展。目前，钙钛矿太阳能电池的最高认证效率已达27%。然而，器件的稳定性仍然是阻碍其大规模商业化的因素之一。众所周知，钙钛矿活性层对于太阳能电池的稳定性起着关键作用。本钙钛矿材料稳定性数据集由苏州大学2020-2024年的实验研究产出，包含5种钙钛矿材料在湿度~10%、温度85 ºC的环境下，校准后为1个标准太阳强度（AM1.5G，1000 W/m2）的模拟太阳光源持续照射下，荧光强度、吸收强度、带隙、载流子迁移率以及缺陷态密度等随时间的变化，以及薄膜老化实物照片等丰富数据。数据采集涵盖紫外-可见吸收、荧光光谱、空间电荷限制电流等测试流程，且经严格把关，多组数据验证，可靠性高。该数据集能深度挖掘不同钙钛矿活性层组分与稳定性之间的关系，为后续筛选高稳定性钙钛矿活性层组分提供理论支撑，具有重要价值。

Perovskite solar cells (PSCs), as a novel photovoltaic technology, have undergone rapid development over the past decade. Currently, the highest certified efficiency of perovskite solar cells has reached 27%. However, the stability of the devices remains one of the main obstacles hindering their large-scale commercialization. As is well known, the perovskite active layer plays a critical role in the stability of solar cells. This perovskite material stability dataset was generated from experimental studies conducted by Soochow University between 2020 and 2024. It contains comprehensive data for 5 types of perovskite materials, including the time-dependent changes in fluorescence intensity, absorption intensity, band gap, carrier mobility, defect state density and other parameters under continuous irradiation with a simulated solar light source calibrated to 1 sun intensity (AM1.5G, 1000 W/m²) in an environment with humidity ~10% and temperature at 85 ºC, as well as physical photos of aged thin films and other rich datasets. The data collection covers test procedures such as ultraviolet-visible (UV-Vis) absorption spectroscopy, fluorescence spectroscopy, space charge limited current (SCLC) measurement and others. All data have been strictly reviewed and verified through multiple sets of experiments, ensuring high reliability. This dataset can facilitate in-depth exploration of the relationship between the composition of different perovskite active layers and their stability, providing theoretical support for the subsequent screening of high-stability perovskite active layer components, and thus holds significant research value.
