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...

| description | 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 increased by increasing the Ge contents. The highest conversion efficiency of 6.05% was obtained for the 12.5% Ge added device in an air atmosphere and the increase of efficiencies would be due to the promoted formation of photoactive α-formamidinium cesium lead triiodide perovskite crystals. |
