Raw Data for Azetidinium Lead Iodide for Perovskite Solar Cells

Here we prepare azetidinium lead iodide for the first time. Azetidinium lead iodide is a stable, bright orange material which does not appear to form a 3D or a 2D perovskite. It was successfully used as the absorber layer in solar cells. We also show that it is possible to make mixed cation devices by adding the azetidinium cation to methylammonium lead iodide. Mixed azetidinium-methylammonium cells show improved performance and reduced hysteresis compared to methylammonium lead iodide cells.

This dataset includes all structural and electrochemical raw data, including thin film XRD, UV/Vis, Cyclic Voltammetry and Mott Schottky measurements. It also includes the main parameters (Efficiency, Open Circuit Voltage, Short Circuit Current Density, Fill Factor) for all those made. The raw data includes JV curve data of the best pixel from each set, a stabilised efficiency measurement for the MAPI, A1 and A2 cell and an EQE measurement of the best overall pixel.

我们首次制备出氮杂环丁烷鎓碘化铅（azetidinium lead iodide）。该材料为稳定的亮橙色物质，未观察到形成三维或二维钙钛矿结构，已成功用作太阳能电池的吸收层。此外，我们还证明，通过向甲基铵碘化铅中添加氮杂环丁烷鎓阳离子，可制备混合阳离子器件。与纯甲基铵碘化铅电池相比，氮杂环丁烷鎓-甲基铵混合阳离子电池表现出更优的性能且滞后现象减少。

本数据集包含所有结构与电化学原始数据，包括薄膜X射线衍射（XRD）、紫外-可见光谱（UV/Vis）、循环伏安法（Cyclic Voltammetry）及莫特-肖特基测试数据。同时，数据集还涵盖所制备器件的主要参数（效率、开路电压、短路电流密度、填充因子）。原始数据包括每组最佳像素的电流-电压（JV）曲线数据、MAPI、A1及A2电池的稳定效率测试数据，以及整体最佳像素的外量子效率（EQE）测试数据。
