Book excerpt: The current climate crisis is a great concern to humankind due to the devastating effects of the consistent rise of anthropogenic greenhouse gases. A viable alternative to reducing greenhouse gas emissions is the development of solar harvesting technologies. The need to develop new semiconductor materials with more capacity to absorb light and convert it into electricity is rapidly growing. A promising class of materials for this purpose are copper-based ternary chalcogenides such as CuCrS2, CuSb1-xBixS2, and Cu3VS4.The synthesis and characterization of copper-based ternary chalcogenides nanocrystals (NCs) have gained popularity in the scientific community due to their novel, physical, chemical, optical, electronic, magnetic, and mechanical properties. NCs can be precursors to the next-generation nanoparticle-based thin film solar cells. This generation of thin film solar cells is advantageous in terms of the compounding benefits. Materials in the forms of NCs offer size, and morphology-dependent properties, high absorption coefficients, and tunable bandgaps. Nanoparticle-based thin film solar cells use very thin layers of material, lowering their production cost while making the systems flexible, more efficient, and compatible with new and existing infrastructure.This dissertation addresses several challenging issues and realizes the successful fabrication of novel CuCrS2, CuSb1-xBixS2 (x=1, 0.18), and Cu3VS4 NCs-based thin films. These systems were synthesized using two different thermal decomposition methods: heat-up (HU) and hot-injection (HI). This dissertation presents a detailed study involving the synthesis and characterization of the above-mentioned semiconductors by applying the developed nano-to-thin film approach. Their optical and electrical properties were explored, and their respective optical bandgaps were determined using UV-vis and electron energy loss spectroscopy (EELS). The ability of the fabricated thin films to generate a photocurrent under sunlight irradiation was explored, reporting their responsivities and current conversion efficiencies.
