Pow(d)ering up: FAPI perovskite nanopowders for air-processed blade coated perovskite solar modules.

ABSTRACT: Formamidinium lead iodide (FAPI) is the most prominent perovskite material utilized in the fabrication of single-junction perovskite solar cells. However, the cubic α-phase perovskite is difficult to retain in precursor solutions for extended periods due to thermodynamic instability, which promotes the formation of the yellow δ-phase. In this study, we demonstrate the fabrication of solar cells and modules from FAPI powders synthesised using a single-step method with a non-hazardous solvent and routine purity grade lead iodide. The pre-synthesised α-FAPI and CsFAPI powders demonstrated considerable potential for scalability and reproducibility. It was observed that similar efficiencies were achieved in small-area cells and mini-modules fabricated using an industrially adaptable blade coati
