In essence, interfacial engineering in perovskite solar cells involves fine-tuning the chemical and physical properties of interfaces to optimize charge transport, diminish recombination, improve stability, and enhance the overall device performance [34, 35]. The performance and longevity of PSCs are significantly impacted by their interfaces.
Recent advances in the interfacial materials have unlocked a wide range of chances for their applications in other photovoltaic systems, such as hybrid solar cells, kesterite/perovskite solar cells, and quantum dot solar cells, etc.
Improves the overall quality of the interface by reducing surface recombination, enhancing carrier lifetime, and improving overall device stability. Optimizes the interaction of incident photons with the solar cell material, ensuring maximum absorption for efficient energy conversion.
However, their practical application faces limitations due to issues like sensitivity to moisture, ion migration, and interface defects, affecting their stability and lifespan. This work delves into the critical role of interface materials in enhancing the stability and effectiveness of perovskite solar cells.
Interfaces and interfacial layers hold critical roles within solar cells, profoundly influencing the efficiency and functionality of these devices. Interfaces serve to facilitate the crucial process of charge separation and collection within a solar cell .
Testing and optimizing interface materials virtually to reduce experimental trial and error can also minimize device imperfections at interfaces. Protecting perovskite interfaces from external elements using encapsulation techniques should be addressed carefully in order to counter the problem of stability issues in perovskite solar cells.
