Abstract

The invention discloses a preparation method for a metal sulfide catalytic electrode and application thereof. According to the invention, metal element or any one form or more than one form of metal sulfide is resolved in hydrazine together with a sulfur element or together with any one form or more than one form of sulfur ammonium salt or sulfur hydrazonium salt, thereby forming a NH4 or N2H5 kation; the metal and the sulfur element form a precursor solution of an anion; the precursor solution is coated on the transparent conductive substrate; and the obtained transparent conductive substrate adsorbing the precursor is subjected to heating and annealing processing, thereby obtaining the metal sulfide catalytic electrode.

Description

technical field [0001] The invention relates to the technical field of quantum dot sensitized solar cell counter electrode preparation, in particular to a preparation method and application of a metal sulfide catalytic electrode. Background technique [0002] Solar cells are one of the most effective technical solutions among various clean energy technologies, and it is of great significance to solve energy and environmental problems in the process of human development. In recent years, many new solar cell technologies have emerged, and inorganic semiconductor sensitized solar cells are the representative of low-cost cells. Inorganic semiconductor quantum dot-sensitized solar cells generally use narrow-bandgap inorganic semiconductor quantum dots as photosensitizers, deposit them on wide-bandgap oxide semiconductor thin film electrodes, and assemble them with electrolytes and counter electrodes to form cells. [0003] The commonly used electrolyte for inorganic semiconducto...
