Alicyclic Lewis Bases Enable 100 °C-Processed α-FAPbI3 Inverted Perovskite Solar Cells

Formamidinium lead iodide (α-FAPbI3) perovskite, despite its ideal bandgap, requires high-temperature (≥150 °C) annealing for the δ-to-α phase transformation, hindering its application in low-temperature processed inverted perovskite solar cells (PSCs), particularly on flexible substrates. Herein, we demonstrate that...
