Solar Cells: Triamine‐Based Aromatic Cation as a Novel Stabilizer for Efficient Perovskite Solar Cells (Adv. Funct. Mater. 44/2019)

In article number 1905190, Byungwoo Park and co-workers present the role of 1,2,4-triazole as a novel stabilizer for organometal-halide perovskites. 1,2,4-traizole has an aromatic structure with triamine and a low-dipole framework, improving the optical/electrical properties and stability of materials and devices. Considering the intense attention on the stability problems in perovskites, minimal degradation under extreme conditions (85 °C/85% relative humidity) are examined to reveal the superior role of 1,2,4-triazole.
