Method for manufacturing ZnO/CuInS<2> nanorod film with core-shell structure

Abstract

The invention belongs to the technical field of manufacture of films, and particularly discloses a method and relevant technological parameters for manufacturing a ZnO / CuInS<2> nanorod film with a core-shell structure. The method for manufacturing the ZnO / CuInS<2> nanorod film is a medium template conversion method, and includes growing a ZnO nanorod on ITO (indium tin oxide) conducting glass by a hydrothermal process by means of using zinc nitrate [Zn(NO<3>)<2>] / hexamethylene tetramine (HMT) aqueous solution as a growth system; then performing water bath by using thioacetamide (TAA) as a reagent to obtain a ZnO / ZnS nanorod film with a core-shell structure; allowing the obtained sample to stand in triethylene glycol (TEG) solution of copper nitrate [Cu(NO<3>)<2>] for a period of time to obtain a medium template of the ZnO / CuS nanorod film with the core-shell structure; and placing the obtained sample in TEG solution of indium chloride (InCl<3>), and enabling the obtained sample to be subjected to high-temperature hydrothermal reaction in a hydrothermal kettle so as to obtain the ZnO / CuInS<2> nanorod film with the core-shell structure on the surface of the ITO conducting glass. Influence of the technological parameters such as the concentration of the TAA, the concentration of the [Cu(NO<3>)<2>] and the hydrothermal reaction time to the structure and the performance of the film is discussed, and the optimal technological parameters for manufacturing the high-performance ZnO / CuInS<2> nanorod film with the core-shell structure are obtained.

Description

technical field [0001] The invention belongs to the technical field of thin film preparation, specifically a method for preparing ZnO / CuInS 2 Methods and associated process parameters for core-shell structured nanorod thin films. technical background [0002] Energy is the material basis for the existence of modern human society, and it is also the direct driving force for the development of human society. With the development of social economy and the rapid growth of population, the energy problem has increasingly become one of the major problems that human beings need to solve urgently. New energy and renewable energy are one of the most decisive technical fields in the development of the world economy in the 21st century. Since the first monocrystalline silicon solar cell came out in 1954, people have placed great hopes on using semiconductor solar cells to solve the energy crisis. As early as the "Sixth Five-Year Plan", the Chinese government included the research and ...

Problems solved by technology

However, the stable pH of ZnO is 7-12, so in the presence of some acidic dyes or electrolytes, it will be corroded to a certain extent. In addition, the electrons injected into ZnO will also recombine with dyes or electrolytes to a certain extent.
