The rapid improvement of perovskite solar cells has made them the rising star of the photovoltaics world and of huge interest to the academic community. Since their operational methods are still relatively new, there is great opportunity for further research into the basic physics and chemistry around perovskites.
In the field of perovskite solar cell research, the most studied materials are hybrid organic/inorganic metal halides.
Perovskite solar cells have surprising intrinsic properties like excellent charge transport, dielectric constants, and less exciton binding energy with high device performance. The power conversion efficiency (PCE) of perovskite solar cells depends upon the specific functions of each layer composition and architecture.
