Problems solved by technology

The trivalent magnetic iron atoms replace the atoms of III, but the d-type conduction band makes the band gap drop sharply to 0.5~0.6eV
[0010] The preparation methods of copper-based solar cell nanomaterials reported in the literature mainly include gas-phase methods and liquid-phase methods, and gas-phase methods mainly include Spray Pyrolysis, RF Sputtering, and vapor phase deposition. Vapor deposition and radio frequency sputtering require expensive high-vacuum systems, complex process operations, low yields, and high costs, which are not conducive to large-scale industrial production
However, the products prepared by spray pyrolysis are easy to form impurity phases, which is not conducive to the light absorption of solar cells.

Embodiment 1

[0038] 2mmolCuCl 2 and 2mmolInCl 3 4H 2 O The two powders were mixed in a one-necked flask, and then 10mmol of sodium oleate was added, followed by 10ml of water, 15ml of ethanol and 30ml of n-hexane. It was heated to reflux at 60° C. for 4 hours to obtain a separated two-phase liquid. After separating the layered liquid with a separatory funnel, take the upper oil phase and evaporate ethanol and n-hexane at 70°C, and then evaporate the remaining water at 110°C to obtain a waxy mixture of copper oleate and indium oleate.

Description

technical field [0001] The invention relates to a method for preparing a copper-based nanometer solar cell material, which belongs to the field of new energy materials, and in particular to a method for preparing high-quality monodisperse nanocrystals using a metal compound as a precursor by using a high-temperature organic solvent pyrolysis method. Background technique [0002] Solar energy is an inexhaustible clean energy, and it is the ultimate energy to replace traditional unsustainable fossil energy. Solar cells are a renewable solar power generation method based on the photovoltaic effect, which does not produce greenhouse gases such as carbon dioxide during the power generation process, and is an environmentally friendly power generation method. At present, monocrystalline silicon and polycrystalline silicon solar cells have been mass-produced on a large scale. Due to the low absorption coefficient of silicon, a certain thickness is required, and materials will be add...
