The present application relates to the technical field of lithium ion batteries, in particular to a core-shell structure binder for lithium battery carbon-coated current collector, its preparation method and application, the present application takes polyacrylonitrile seed emulsion, passes into nitrogen, adds shell monomer pre-emulsion, potassium persulfate aqueous solution, warms, reacts, cools, adds anhydrous ethanol, centrifugal, removes impurities, dries, grinds, obtains core-shell structure binder. The compact, hydrophobic shell layer of the core-shell structure binder acts as a barrier to prevent oxygen and moisture in the air from entering the core layer, thereby protecting the cyano group of the polyacrylonitrile in the core layer; when the lithium battery carbon-coated current collector is coated with the positive electrode material, the N-methyl pyrrolidone in the positive electrode material can selectively permeate the shell layer and swell with the cyano group of the polyacrylonitrile in the core layer, thereby improving the interlayer adhesion between the carbon-coated layer and the positive electrode material through subsequent drying, and solving the problem of poor stability of traditional polyacrylonitrile-based binders.

This invention discloses an inverse perovskite solar cell and its fabrication method that utilizes a tetrathiofulvalene derivative to regulate the self-assembled monolayer (SAM) assembly structure. The invention uses bis(carbazolium phosphate) SAM-4PABCz as the hole-selective interface layer, employs an ethanol / NMP mixed solvent system, and introduces a tetrathiofulvalene (TTF) derivative as a dopant. By leveraging the steric hindrance effect and non-covalent intermolecular interactions of the TTF derivative, the out-of-plane π-π interactions between bis(carbazolium phosphate) molecules are weakened, inducing the molecules to shift from a high-tilt-angle "standing" stacking of SAM molecules to a low-tilt-angle near-flat arrangement. This regulation strategy effectively suppresses island-like aggregation of SAMs, reduces the interface defect state density, promotes uniform and ordered molecular stacking, and forms a uniform and dense hole-selective contact interface.
