Although perovskite solar cells are more efficient and less expensive than traditional silicon solar cells, perovskite has, until now, been limited by its lack of long-term stability.

1 Introduction. In recent years, solar energy has drawn an intense attention as the most abundant clean and renewable energy. Many kinds of solar cell devices (e.g., silicon, thin film, organic, organic–inorganic (i.e., hybrid) perovskite) have been developed to convert solar energy directly into electricity.

The PSCs are the next generation of the PV market as they can produce power with performance that is on par with the best silicon solar cells while costing less than silicon solar cells.
Hashini Perera, lead author of the study at the University of Surrey, said: “In the past, metal oxides have been shown to either benefit or degrade the performance of perovskite solar cells. We’ve identified aluminium oxide, which can improve performance and minimises the drop in efficiency during conditioning of perovskite solar cells.
On the other hand, the operating mechanics of silicon solar cells, DSCs, and perovskite solar cells differ. The performance of silicon solar cells is described using the dopant density and distribution, which is modelled as a p-n junction with doping. The redox level in electrolytes impacts the output voltage of a device in DSCs.
Opaque metal act as bottom electrode has the advantage of reducing the production cost of perovskite solar cells. In the previous reports, Al has the risk to react with the mobile ions from halide perovskite which degrades the perovskite photovoltaics performance [ 67, 68 ].
Recently, since the efficiency of the best perovskite solar-cell reached 25.5%, comparable to the best PV cells made of single-crystal silicon, it is optimistic for the perovskite PV cells to be commercial in the future.
Another core problem in the development, production and use of perovskite solar cells is their recyclability. Perovskite recycling is an absolute necessity due to the presence of lead in perovskites.
