In case you haven’t heard of them, perovskite solar cells are what can be used in solar panels, and they have the capability of absorbing solar energy and converting it into electricity that we can use. While the perovskite-based cells show a lot of promise, there are a few major flaws in the material that really can’t be overlooked; mainly their efficiency and durability. However, graphene has come to save the day, as it can be used to enhance the cells and bring them one step closer to being regularly used in solar panels.

Firstly, the pristine form of graphene can be combined with the perovskite, and while alone the perovskite wasn’t too capable of being efficient in high-stress environments, coupled with graphene the overall efficiency of the cells went all the way up to 15%. 

In addition to that, graphene was able to become a major stabilizer in the function of the perovskite. On its own, the active layer of the metal halide was quite susceptible to negative environmental effects (rain, high winds, etc), but with the joint force of graphene, the active layer has been able to stabilize quite nicely, and its solar energy absorbing efficiency had gone from 73% to 80%. 

While the perovskite/graphene solar cells aren’t yet perfect, these tests and experiments have been a major turning point in solar energy production and opened the door to more graphene-based calibrations.
