Ion migration in perovskite materials is a double-edged sword. On the one hand, it can lead to device degradation and performance loss. On the other hand, it can be exploited for new applications, such as energy harvesting and storage.
Latest advances in ion migration research for simultaneous energy harvesting and storage:
In a recent study, researchers developed a perovskite-based energy storage device that can simultaneously harvest and store energy from the environment. The device consists of a perovskite solar cell and a battery. The solar cell converts light energy into electrical energy, which is then stored in the battery. The battery is also able to harvest energy from the environment through ion migration
The researchers developed a new strategy to suppress ion migration in the perovskite solar cell. This strategy involved using a special coating that prevents ions from migrating out of the perovskite layer. The coating also helps to improve the charge collection efficiency of the solar cell.
The researchers also developed a new battery chemistry that is compatible with ion migration. This battery chemistry allows ions to migrate between the electrodes, which allows the battery to be charged and discharged simultaneously.
The new perovskite-based energy storage device is able to harvest and store energy more efficiently than traditional solar cells and batteries. The device is also more stable and has a longer lifespan.
