Abstract

A method for preparing nano-aluminum powder ink for ink-jet printers by emulsification and dispersion method. According to a certain mass ratio, nano-aluminum powder, ethanol, and isopropanol are blended in a container, and the above blended solution is uniformly emulsified and dispersed by high-speed emulsification equipment After a certain dispersion time, add the dispersant to the blend solution in three batches during the emulsification and dispersion process. Add the above emulsion one at a time, and then continue to emulsify the above emulsion for 1.5~3 hours to obtain the nano-aluminum powder ink for inkjet printers with excellent performance. The method of the present invention is applied to the production of thin-film solar cells. The production process is simple and the production cost is low. The thin-film solar cells produced are natural and low-pollution, and the price is reduced. They are suitable for portable electronic products and are very competitive energy substitutes in the future. The program has potential extremely broad practicability and market promotion prospects.

Description

technical field [0001] This patent designs a processing method of nano-aluminum powder ink for inkjet printers, especially a processing method of nano-aluminum powder ink applied to thin-film solar cells. technical background [0002] With the rapid development of human civilization, the demand for energy is also increasing day by day. Traditional petrochemical energy such as oil, natural gas and coal are not only facing the crisis of depletion soon, but also the price is even more severe. fluctuation. In addition, the burning of sun lake energy will produce carbon dioxide and other wastes, which will cause environmental pollution such as greenhouse effect and acid rain. Therefore, the world is paying more and more attention to renewable energy, such as the use of wind power, water conservancy and solar lights, which are natural and low-cost. Polluting energy is a very competitive energy alternative in the future. [0003] The solar energy that this patent is concerned abo...
