Abstract

The invention discloses a preparation method of pattern and size controllable CuInSe2 nanoparticles, and relates to CuInSe2 nanoparticles. The method comprises the following steps that indium trichloride and cuprous chloride are dissolved in an oleylamine solvent, heated, stirred and prepared to form an oleylamine solution of indium trichloride and cuprous chloride; elemental selenium powder is added to the oleylamine solution, stirred and heated, and dissolved; the solution obtained in Step (1) is injected into a solution obtained in Step (2), heated to 190-290 DEG C and reacted for 10-240min; after the reaction is accomplished, a product is cleaned, centrifuged and collected; and the CuInSe2 nanoparticles are obtained. The method can selectively synthesize the CuInSe2 nanoparticles with different sizes and patterns through one step, is low in cost and environment-friendly, and facilitates large-scale production; the sizes and the patterns of the product are controllable; and the repeatability is good.

Description

technical field [0001] The present invention relates to CuInSe 2 Nanoparticles, specifically a CuInSe 2 Nanoparticle morphology and size controllable preparation method. Background technique [0002] Copper indium selenide solar cells are considered to be the most promising and market-competitive type of solar cells in the future due to their high absorption constant, high conversion efficiency, low cost and abundant raw material sources. In the complex structure of copper indium selenide solar cells, copper indium selenide (CuInSe 2 ) The thin film layer is the core material of the battery. Traditional preparation of CuInSe 2 The methods of thin film layers mainly include co-evaporation method, sputtering method, laser induced synthesis method, metal selenide prefabricated layer method, etc. Most of these methods require expensive equipment, and CuInSe 2 The chemical composition of the film layer is difficult to control, and even the use of toxic reagent H is required ...
