Problems solved by technology

Most hydrovoltaic power generation devices do not get rid of the evaporation power generation mode, which can be classified into the concept of "hydrovoltaic battery" proposed by the inventor of this patent in the previous invention patent. The film needs to be as thin as possible, and can only use the heat of the surrounding environment, and Liquid flow can only be driven by capillary force and the vacancies vacated by evaporation, making it difficult to further improve power generation efficiency

Embodiment 1

[0034] (1) Mix the graphene oxide dispersion liquid with a concentration of 2 mg / mL and the alumina nanofiber dispersion liquid with a concentration of 2 mg / mL to obtain a mixed liquid. The diameter of the alumina nanofibers is 100 nm, and the graphene oxide dispersion liquid and the alumina nanofibers The mass ratio of the dispersion liquid is 1:1.

[0035] (2) Put the mixed solution into a polytetrafluoroethylene container, and contact the bottom of the container with liquid nitrogen for 30 minutes to obtain a vertically oriented graphene oxide / alumina nanofiber array. The graphene / alumina nanofiber arrays were freeze-dried for 36 hours.

[0036] (3) The vertically oriented graphene oxide / alumina nanofiber arrays were immersed in a hydrazine hydrate solution and reduced for 2 hours to obtain graphene / alumina nanofiber arrays.

[0037] (4) Mix ethyl cellulose, alumina nanoparticles, alumina nanofibers and absolute ethanol with a mass ratio of 1:10:4:20 and heat and stir at 8...

Abstract

The invention provides a preparation method of a functional array for a photovoltaic generator, which comprises the following steps: preparing a vertically oriented graphene / aluminum oxide nanofiber array, filling channels of the array with ethyl cellulose, aluminum oxide nanoparticles and aluminum oxide nanofiber slurry, and annealing in an air atmosphere; adding waterproof electrodes and wires to the bottom area and the top area of the array respectively, and obtaining the functional array of the photovoltaic generator. The concept of a photovoltaic generator is proposed for the first time,electric energy can be generated by means of directional movement of water flow and used for replacing the function and position of a traditional hydroelectric generator, and a new form is provided for water energy application.

Description

technical field [0001] The invention relates to the field of preparation of hydroelectric generators, in particular to a method for preparing functional arrays for hydroelectric generators. Background technique [0002] Water is closely related to energy and maintains the energy cycle of the earth system, the temperature balance of organisms, and is a natural energy absorber, energy storage, transducer and energy transmitter. Nearly 70% of the energy from solar radiation reaching the surface is absorbed by water, and the annual average power of water absorbing and releasing energy on the earth is as high as 60 trillion kilowatts, which is 3 orders of magnitude higher than the average annual energy consumption of all human beings. Water stores the absorbed heat in the form of thermal energy and kinetic energy, and converts the stored solar energy into mechanical energy and other forms of energy in the form of evaporation, condensation, forming clouds and rain, and making wave...
