Problems solved by technology

However, because ammonia has a strong pungent smell and is harmful to the human body, when too much ammonia is inhaled, it can cause lung swelling and even death
In addition, it is necessary to add an exhaust gas treatment device, which increases the economic cost in the actual application process

Abstract

The invention discloses an antireflection film based on carbon dioxide atmosphere heat treatment and a preparation method and application thereof. The antireflection film is prepared by carrying out heat treatment on a silicon dioxide film in a carbon dioxide-containing atmosphere. According to the method, the visible-near infrared transmittance of the thin film can be remarkably improved only by introducing the atmosphere containing carbon dioxide for heat treatment during thin film annealing, operation is easy, the requirement for preparation conditions is low, cost is low, repeatability is good, the thin film can be formed on a large-area substrate in a coating mode, and industrial application is facilitated.

Description

technical field [0001] The invention belongs to the technical field of optical thin films, and in particular relates to an anti-reflection film based on heat treatment in a carbon dioxide atmosphere, a preparation method and application thereof. Background technique [0002] AR coatings have been widely used in the optical field to increase transmittance and clarity. Due to the current shortage of energy, anti-reflection coatings are also widely used in solar cells to increase transmittance, thereby improving photoelectric conversion efficiency. At present, the main research problem of anti-reflection coating is how to solve its weather resistance and further simplify the steps to improve its transmittance. [0003] Existing studies have shown that SiO 2 Heat treatment of the film will increase the transmittance of the film. However, because ammonia has a strong pungent smell and is harmful to the human body, when too much ammonia is inhaled, it can cause lung swelling an...
