▎ 摘　　要

NOVELTY - System (100) comprises: a carbon fiber yarn layer (102) made by electrospinning the mechanically strong and thermally stable carbon fiber yarns having considerable electrical conductivity; an atomically thin 2D-MX2-layer (two-dimensional, monolayer transition-metal dichalcogenide-layer) (104) i.e. a photoactive semiconductor layer applied to the prepared carbon fiber yarns by chemical vapor deposition; an annealing device for improving the crystalline quality and electrical properties of the prepared layers of carbon fiber yarns coated with 2D MX2 photoactive semiconductors by annealing at 750 degrees C for 1 hour; a graphene layer (108) as a Schottky-barrier-contact for separating changes and for collecting the holes from the photoactive 2D-MX2-layer, where the graphene layer is deposited on the photoactive 2D-MX2-layer by chemical vapor deposition; and a protective unit (110) for applying a final protective capsule to the layers. USE - The system is useful for developing solar cells based on nanofibers for smart nanotextile (claimed). ADVANTAGE - The system produces developed fiber having final thickness of 100 mu , which can be woven into textiles of interest and many other types of wearables. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block representation of the system for developing solar cell-based nanofibers for smart nanotextile.
