| 41. | After light absorption both charge generation as well as charge extraction occurs in the perovskite layer . ]]
|
| 42. | Although the most common perovskite compounds contain oxygen, there are a few perovskite compounds that form without oxygen.
|
| 43. | Although the most common perovskite compounds contain oxygen, there are a few perovskite compounds that form without oxygen.
|
| 44. | Due to the instability of perovskite cells lead may eventually be exposed to fresh water during the use phase.
|
| 45. | The perovskite crystal structure was first described by Victor Goldschmidt in 1926, in his work on tolerance factors.
|
| 46. | Sol-gel routes using tantalum ( V ) ethoxide to generate layered perovskite materials have also been developed.
|
| 47. | The crystal structure of antiperovskite parallels the perovskite structure, with the exception of switching anion and cation positions.
|
| 48. | FRAM relies on the polarization of what amount to tiny magnets inside certain materials like perovskite, from basaltic rocks.
|
| 49. | Associated minerals include ilmenite, zirkelite, apatite, magnetite, perovskite, fluorite, nepheline, pyrochlore and allanite.
|
| 50. | Extremely rare igneous rocks contain as much as 70 % melilite, together with minerals such as pyroxene and perovskite.
