| Abstract Scope |
Antimony selenide (Sb2Se3) emerges as a promising sunlight absorber in thin film photovoltaic applications due to its excellent light absorption properties and carrier transport behavior, attributed to the quasi-one-dimensional Sb4Se6-nanoribbon crystal structure. Overcoming the challenge of aligning Sb2Se3-nanoribbons normal to substrates for efficient photogenerated carrier extraction, we employed a solution-processed nanocrystalline Sb2(S,Se)3-seed on the CdS buffer layer. These nanoseeds facilitated superstrated Sb2Se3 thin film solar cell growth through a close-space sublimation approach. The thin Sb2(S,Se)3-nanoseeds guided the Sb2Se3 absorber growth along a [002]-preferred crystal orientation, ensuring a smoother interface with the CdS window layer. Remarkably, Sb2(S,Se)3-seeds improved carrier transport, reduced series resistance, and increased charge recombination resistance, resulting in an enhanced power conversion efficiency of 7.52%. This cost-effective solution-processed nanoseed planting approach holds promise for advancing chalcogenide-based thin film solar cells in large-scale manufacturing. |
