The development of up-scalable and high-throughput methodologies to fabricate high-efficiency lead halide perovskite solar cells (PSCs) based on α-phase formamidinium lead iodide (FAPbI3) is one of the main challenges of making solar energy economical. In this context, PSCs based on α-phase formamidinium lead iodide (FAPbI3) are receiving special attention as this perovskite has the highest theoretical photoconversion efficiency (PCE). This manuscript reports an easy, fast and environmentally-friendly way to prepare α-FAPbI3 black powders by a microwave-assisted synthesis and their application in solar cells. The α-FAPbI3 powders consist of micrometric particles that can be stored for weeks in a closed vial at ambient conditions. This technique presents an enormous potential for upscaling FAPbI3 powders synthesis prerequisite necessary for large scale commercialization. The performance of the presynthesized FAPbI3-based solar cell was comparable with that of PSCs fabricated with the conventional procedure from precursors solutions, leading to a maximum PCE value of 18.15%, with an VOC=1.07 V, a Jsc=24.28 mA/cm2 and an FF=70%. The presynthesized FAPbI3-based solar cell was further modified through the addition of methylammonium chloride (MACl) in order to study the generality of the approach. The optical band gap for the presynthesized perovskite shifted from ∼1.43 eV to ∼1.55 eV with the MACl addition (30 mol%), indicating the formation of a mixed methylammonium and formamidinium based perovskite material (MAFAPbI3). In addition, the incorporation of MACl led to an increase in the grain size and the disappearance of the residual δ-phase perovskite, thus improving the efficiency of the final device. [-]
