摘要

This review explores the multifaceted roles of transition metal dichalcogenides (TMDs) in advancing solar cell technologies. TMDs, with their unique properties and structural versatility, help address efficiency and scalability issues in solar energy conversion. Various synthesis techniques- chemical vapour deposition, mechanical and liquid-phase exfoliation, and molecular beam epitaxy- are discussed. The article elaborates on the mechanisms of Mo, W, V, and Re-based TMDs in light absorption, charge generation, and electron transport. It also covers their structural characteristics, where a transition metal is sandwiched between two chalcogen atoms, enabling unique electronic and optical properties. The review also discusses various performance enhancement strategies, including bandgap engineering, interface engineering, defect engineering, and hybrid architectures, to improve the efficiency of TMD-based solar cells. Also, highlights how the TMD morphology of nanosheets, nanoribbons, and nanoparticles affects efficiency through grain boundaries, edge states, and surface defects. Despite progress, challenges remain in commercial integration. A better understanding of interface physics in TMD-based devices could significantly enhance efficiency and durability, paving the way for broader solar adoption.
