INORGANIC AND ORGANIC BUILDING BLOCKS FOR ECO-FRIENDLY SOLAR CELLS

This PhD thesis focuses on the development of eco-friendly solar cells using abundant, non-toxic, and low-impact materials. Copper Zinc Tin Sulphide (CZTS) nanoparticles were synthesised through an eco-friendly route, deeply characterised, and integrated into photovoltaic devices with various buffer layers and architectures. Hybrid systems combining CZTS with organic materials were also investigated, paving the way towards the development and understanding of inorganic-organic solar cells. Finally, the sulphur-rich molecular system, Cu(dttt)₂, was studied, highlighting potential applications in photovoltaics and quantum information. The work aims to provide innovation in sustainable solar technologies, aligned with global climate goals.
