“…The fact that the attractive forces among graphene sheets cause the graphene sheets to restack, which reduces the number of active sites available, is one of the primary disadvantages of using graphene in fuel cells. Three-dimensionally structured graphene has a customized hierarchical porosity and curved non-planar shape, which can effectively address this problem [ 117 ]. Rapid electron movement is made possible by the continuous conductive network, and ion transport is facilitated by the 3D graphene’s interconnected hierarchical porosity [ 118 ].…”

Fuel cells are at the forefront of modern energy research, with graphene-based materials emerging as key enhancers of performance. This overview explores recent advancements in graphene-based cathode materials for fuel cell applications. Graphene’s large surface area and excellent electrical conductivity and mechanical strength make it ideal for use in different solid oxide fuel cells (SOFCs) as well as proton exchange membrane fuel cells (PEMFCs). This review covers various forms of graphene, including graphene oxide (GO), reduced graphene oxide (rGO), and doped graphene, highlighting their unique attributes and catalytic contributions. It also examines the effects of structural modifications, doping, and functional group integrations on the electrochemical properties and durability of graphene-based cathodes. Additionally, we address the thermal stability challenges of graphene derivatives at high SOFC operating temperatures, suggesting potential solutions and future research directions. This analysis underscores the transformative potential of graphene-based materials in advancing fuel cell technology, aiming for more efficient, cost-effective, and durable energy systems.

“…It denotes the cumulative resistance encountered by the -103 current as it traverses through the cell components sequentially [75]. This resistance originates from diverse sources including the TCO substrate, photoelectrode material, interfaces, and metal back contact resistance [76]. Minimising series resistance is essential for enhancing ssDSSC efficiency, as elevated series resistance can result in voltage drops and diminished power generation.…”

Among the emerging photovoltaic technologies, solid‐state dye‐sensitised solar cells (ssDSSCs) have attracted considerable interest due to their cost‐effective production, adjustable characteristics, and potential for lightweight and flexible applications. Nevertheless, achieving efficiencies comparable to established technologies, such as perovskite and silicon‐based solar devices, have proven challenging. Herein, the device structure, Pt/PEDOT: PSS/N719 dye/PC61BM/ITO is investigated theoretically using the solar cell capacitance simulator (SCAPS‐1D). Groundbreaking advancement is introduced in ssDSSC design, achieving remarkable theoretical power conversion efficiency of 20.73%, surpassing the performance reported in traditional dye‐based solar cell technologies. The model ssDSSC demonstrates an exceptional Fill factor of 86.64%, indicating efficient current collection; along with a modest short‐circuit current density (Jsc) of 22.38 mA/cm2 and an impressive open‐circuit voltage (Voc) of 1.0691 V, highlighting efficient light absorption and charge separation. Mott–Schottky capacitance analysis and parasitic resistances (series and shunt) have been thoroughly discussed. Despite the fact that only numerical simulation is involved, the proposed ssDSSCs structure gives insights into the fabrication of a highly efficient solar cell that can be injected into the production workflow in order to advance the photovoltaic technology of the solid‐state DSSC.
