This comprehensive review evaluates recent advances in graphene production and its application in solar cells, focusing on dye-sensitized, organic, and perovskite devices. Key findings include a 20.3% improvement in energy conversion rates in graphene-perovskite photovoltaic cells and a 10% boost in bulk heterojunction (BHJ) cells. Graphene's 2D structure enhances device stability and facilitates charge transport. The review also highlights the role of graphene derivatives in solar PV systems, addressing challenges and future prospects. The study discusses various synthesis techniques for graphene, such as chemical vapor deposition (CVD) and atomic layer deposition (ALD), and their impact on material properties. Additionally, it explores the integration of graphene in organic solar cells (OSCs), dye-sensitized solar cells (DSSCs), and perovskite solar cells (PSCs), emphasizing the benefits of enhanced stability, efficiency, and performance. The review concludes by discussing the potential of 2D materials, including graphene, in advanced solar cell technologies, highlighting the need for further research to achieve cost-effective, flexible, and eco-friendly solar energy solutions.This comprehensive review evaluates recent advances in graphene production and its application in solar cells, focusing on dye-sensitized, organic, and perovskite devices.
