Nonalloyed α-phase formamidinium lead triiodide solar cells through iodine intercalation | Science
Formamidinium lead triiodide (FAPbI3) is considered the most promising composition for high-performing single-junction solar cells. However, nonalloyed α-FAPbI3 is metastable with respect to the photoinactive δ-phase. We have developed a kinetic …
