The rising need for energy consumption, along with the ease of utility, directs research toward the manufacture of highly functional energy systems. To fulfil current energy demands, scientists, and modern industries all over the world are trying to observe different low-cost raw materials and are working to develop highly effective, lightweight, portable, and environmentally friendly energy conversion systems such as solar cells. As a result, paper electrodes are playing an essential role in modern flexible, lightweight, and portable components of such devices. This research work reports the synthesis of materials and fabrication of eco-friendly, flexible, lightweight paper electrodes for dye-sensitized solar cells. Natural fibres (Musa fibres) extracted from self-growing plants are incorporated to give mechanical stability and function as non-toxic natural binders for electrode development. Nanostructured metal sulfide e.g., Molybdenum disulfide (MoS2) is being used in this research work because it has low cost, can provide inherent material stability, and has the ability to offer a large surface area to enhance the kinetics required for fast charging. The current work is an approach to fabricate MoS2/LC composite materials for the development of high-power density and improved cyclical stable electrodes for DSSC applications. MoS2 was synthesised using the microwave-assisted method. Musa fibres were incorporated with MoS2 and used as a natural binder for the fabrication of paper electrodes. Galvanostatic charge-discharge testing was used to analyse and compare the prepared electrodes for energy conversion applications using a three-electrode system. Other characterizations e.g., XRD, FTIR, and Raman confirmed the successful formation of MoS2 and MoS2/LC composite. The electrode demonstrated high electrochemical response, specific capacitance, and cyclic stability. As a result, the fabricated electrodes are suitable for use in energy conversion applications.enDepartment of PhysicsSP20NATURAL SCIENCES::PhysicsDye-Sensitized Solar CellMolybdenum DisulfideLignocellulose Fibre- based CompositesDr. Muhammad Aamir RazzaqThesis
