1. Perovskite , apatite, nepheline and garnet may also be present.2. At high temperatures, lead titanate adopts a cubic perovskite structure. 3. Associated minerals include zircon, aegirine, apatite, perovskite and columbite. 4. Natural silicate perovskite was discovered in a heavily shocked meteorite. 5. It is an optically transparent ceramic oxide with a distorted perovskite structure. 6. For perovskite solar cells, the internal quantum efficiency approaches 100 %. 7. This also enables the integration of other thin film perovskite oxides onto silicon. 8. It is black in color and crystallizes in a distorted hexagonal perovskite structure. 9. TiO 2 which is coated with the perovskite absorber. 10. The post-perovskite phase has implications for the mantle responsible for plate tectonics.
