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.
