specific Embodiment 1

[0017] Add 10mL of TEOS (tetraethyl orthosilicate) into a cup filled with 50mL of absolute ethanol, seal it with plastic wrap, and stir on a constant temperature multi-head magnetic stirrer for 15 minutes. Add 0.92mL of HCl solution with pH=1 and 1.8mL of quantum dot solution with a concentration of 10% into another cup filled with 50mL of absolute ethanol, seal it with plastic wrap, and put it on a constant temperature multi-head magnetic stirrer to stir for 15 minutes . When stirring is complete, slowly add the solution in the second cup to the first cup using a separatory funnel. After all the solution in the second cup is added dropwise into the first beaker, seal it with plastic wrap, put it on a constant temperature multi-head magnetic stirrer and stir for 30 minutes. Leave the cup for a few days, and finally use a puller to coat it.

Abstract

The invention provides a method for manufacturing an antireflection film for a solar battery. The photovoltaic efficiency of a solar panel is improved in a film coating and quantum dot adding mode. The antireflection film is manufactured through preparing a sol, and in addition, quantum dots are added during the sol preparation, so that partial short-wavelength light is converted to the visible light waveband, the available energy is increased, the photovoltaic efficiency of the solar panel is improved, and finally, a coater is used for film coating. The method provided by the invention has the advantages that a sol-gel film coating method is adopted for manufacturing the coated film, the equipment is simple, in addition, the operation is convenient, the operation can be carried out on substrates with irregular shapes or large dimensions, the cost is lower, and the industrial mass production is convenient.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a solar cell method for making an anti-reflection film. Background technique [0002] With the development of the times, the status of energy in human society is becoming more and more important. Therefore, a large number of scientists in various countries are devoted to the research of energy issues, and the research on solar energy is one of the key points. From the perspective of reserves, solar energy is the fundamental source of most of the energy on the earth. The solar energy that the earth can receive in a year is as high as 1.8×10kW·h. Solar energy can also be regarded as inexhaustible. . If human beings can effectively develop and utilize solar energy, it will greatly alleviate the pressure on human beings caused by energy. From the perspective of environmental protection, solar energy will not cause pollution like thermal power generation, nor will it affect the orig...
