Graphene-Based Batteries vs. Lithium-Ion: The Future of HOME
Graphene, a single layer of carbon atoms arranged in a two-dimensional lattice, has sparked considerable interest in the field of energy storage. Its remarkable electrical
The use of graphene improves charge collection and mechanical flexibility, making it a promising material for next-generation organic photovoltaics. 4. The energy band diagram illustrates the energy levels of various materials used in graphene-based solar cells, including FTO, TiO₂, CH₃NH₃PbI₃, reduced graphene oxide (RGO), and Au.
Graphene brings along advantages of higher flexibility, transparency, and potentially lower costs. Light Absorbing Layer: This layer absorbs sunlight and converts its energy into electron-hole pairs (excitons). It can be made from silicon or organic materials.
Graphene-based solar cell architectures, such as graphene-silicon heterojunction and graphene-organic solar cells, hold great promise for enhanced efficiency and cost reduction. However, a key challenge lies in optimizing the interface between graphene and adjacent materials.
The properties of graphene, for instance, high electron mobility and strength, interact with solar cell materials quite differently, underscoring the importance of compatibility and stability at the interface between the graphene and the rest of the materials in order to forestall degradation and ensure the prolonged life of the solar cell .
