Abstract

The invention discloses a porous flaky CuInSe2 nanometer material and a preparation method thereof, which adds a new variety to the CuInSe2 nanostructure material and fills up the gap in the prior art at home and abroad. The CuInSe2 nanostructure material has a sheet structure, the nanometer size is 5-20 microns, and the thickness of the nanosheet is 200-600 nanometers. The surface of the nanosheet is very rough, assembled by particles with a particle size of 20-40 nanometers, rich in a large number of microporous structures with a pore size of 20-25 nanometers. The porous flaky CuInSe2 nanomaterial of the present invention is prepared by a mixed solvothermal method, that is, using CuCl2 2H2O, InCl3 4H2O and SeO2 as raw materials, in a mixed solvent of ethylene glycol and ethylenediamine, through a one-step solvothermal reaction. to make. The porous flaky CuInSe2 nanometer material obtained in the invention is a solar cell material with novel structure and superior performance, and can be developed and applied in the field of solar cells. The preparation process of the invention has easy-to-obtain raw materials, simple equipment, low cost, easy operation and good repeatability, and is suitable for industrialization.

Description

technical field [0001] The invention relates to the field of preparation of semiconductor optoelectronic nanomaterials, in particular to a porous flaky CuInSe 2 Nanomaterials and their preparation methods. Background technique [0002] Solar energy is a clean, clean, non-polluting, inexhaustible natural energy source. Converting solar energy into electrical energy is an important technical basis for large-scale utilization of solar energy. Academia and industry generally believe that the development of solar cells has entered the third generation, that is, copper indium selenide (CuInSe) 2 , CISe) compound thin-film solar cells and thin-film Si-based solar cells. CISe solar cells are polycrystalline thin-film cells developed since the early 1980s. The band gap of CISe compound is about 1.04eV, and it has a high absorption coefficient, so it is suitable as a photovoltaic material. CISe battery has become one of the most promising solar cells in this century due to its low...
