Embodiment Construction

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0026] Such as Figure 1 to Figure 3 Shown is an example diagram of a selenium vapor preparation device provided by an embodiment of the present invention, which includes a base 1, a box body 2 arranged on the base 1, a selenium solid heating device 3 arranged in the box body 2, and a box body 2. There is an exhaust port for vacuuming and an air inlet (not shown in the figure) for filling the box 2 with nitrogen. In this way, the box 2 can be evacuated to the box 2 It is filled with nitrogen to provide protection for the selenium solid heating device 3 in the box 2, isolate the selenium vapo...

Abstract

The invention is applicable to the technical field of selenium vapor preparation and discloses a preparation device for selenium vapor, which includes a base, a box body arranged on the base, and a selenium solid heating device arranged in the box body, and the box body is provided with a device for vacuuming The exhaust port for use and the air inlet for filling nitrogen; the selenium solid heating device includes a heating tank with an inner cavity, a heating wire wound on the outer wall of the heating tank, and the preparation device for selenium vapor also includes the inner cavity of the heating tank The connected selenium vapor application module is provided with a first control valve on the heating tank to control the on-off state between the heating tank and the selenium vapor application module; the heating tank is connected with an inlet pipe for filling nitrogen into the heating tank . In the present invention, by setting a heating tank in the sealed box, the selenium solid can be evaporated into selenium vapor in the heating tank, and nitrogen is filled in the box, so that the heating tank can be surrounded by a nitrogen layer, providing a safer environment for the selenium vapor. Protective measures, so that selenium vapor can be prepared safely and effectively.

Description

Technical field [0001] The invention belongs to the technical field of selenium steam preparation, and in particular relates to a preparation device and a preparation method of selenium steam. Background technique [0002] Copper Indium Gallium Selenide is a new type of thin film material, which has the advantages of good absorption, thin thickness, radiation resistance, large power generation from weak light, good solar spectrum matching, and high conversion efficiency. It has been widely recognized and used as a thin and light photovoltaic material in the future. The second choice. The most commonly used method for preparing the copper indium gallium selenium absorption layer is to prepare a metal prefabricated layer and then perform post-selenization. The high-temperature selenization method usually includes three methods: selenium vapor introduction, hydrogen selenide introduction, and heat treatment of the evaporated selenium preform layer. Hydrogen selenide is not widely u...
