摘要
Antimony selenide (Sb 2 Se 3 ) 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 Sb 4 Se 6 ‐nanoribbon crystal structure. Overcoming the challenge of aligning Sb 2 Se 3 ‐nanoribbons normal to substrates for efficient photogenerated carrier extraction, we employed a solution‐processed nanocrystalline Sb 2 (S,Se) 3 ‐seeds on the CdS buffer layer. These seeds facilitated superstrated Sb 2 Se 3 thin film solar cell growth through a close‐space sublimation approach. The Sb 2 (S,Se) 3 ‐seeds guided the Sb 2 Se 3 absorber growth along a [002]‐preferred crystal orientation, ensuring a smoother interface with the CdS window layer. Remarkably, Sb 2 (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 seeds planting approach holds promise for advancing chalcogenide‐based thin film solar cells in large‐scale manufacturing.
