Promoted Formation of Photoactive α-Formamidinium Cesium Lead Triiodide Perovskite Crystals by Germanium Addition

Promoted Formation of Photoactive α-Formamidinium Cesium Lead Triiodide Perovskite Crystals by Germanium Addition

Germanium (Ge) was added to formamidinium cesium lead triiodide perovskite crystals and the microstructures and photovoltaic properties were investigated. The Ge addition stabilized the α-phase of the perovskites and suppressed formation of the δ-phase. X-ray diffraction peaks of the α-phase increas...
