Abstract

The invention relates to the technical field of selenium steam preparation and provides a preparation device for selenium steam. The preparation device comprises a pedestal, a box body arranged on the pedestal, and a selenium solid heating device arranged in the box body. The box body is provided with an exhaust port used for vacuum pumping and a gas inlet used for injecting nitrogen. The selenium solid heating device comprises a heating tank with an inner cavity and a heating wire wound around the outer wall of the heating tank. The preparation device for selenium steam also comprises a selenium steam application module communicating with the inner cavity of the heating tank. The heating tank is provided with a control valve controlling the communicating state of the heating tank and the selenium steam application module. The heating tank communicates with a gas inlet pipe used for injecting nitrogen to the heating tank. According to the invention, the sealed box body is inside provided with the heating tank which can evaporate selenium solid into selenium steam and the box body is filled with nitrogen to make the heating tank be surrounded by the nitrogen layer, so that safer protection measures are provided for selenium steam and selenium steam can be prepared safely and effectively.

Description

technical field [0001] The invention belongs to the technical field of selenium vapor preparation, and in particular relates to a preparation device and a preparation method of selenium vapor. 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 under weak light, good solar spectrum matching, and high conversion efficiency. Second choice. The most commonly used method to prepare CIGS absorber layer is to prepare metal prefabricated layer and then perform post-selenization, and high-temperature selenization methods usually include three methods: selenium vapor introduction, hydrogen selenide introduction, and heat treatment of evaporated selenium prefabricated layer. Hydrogen selenide is not commonly used in industry due to its highly toxic properties, and the other two methods involve the preparation of selenium vapor, which ...
