Abstract

The application relates to a reaction device for online generation of gaseous hydride. The gaseous hydride generation zone is located between the hydrogen source ionization zone and the gaseous hydride reaction zone. One end of the shell is provided with the hydrogen source ionization zone. The other end of the connected air inlet is provided with an exhaust port connected to the hydride reaction zone. The exhaust port is connected to a first vacuum pump for vacuuming the inside of the casing. The first vacuum pump is connected to an exhaust gas treatment unit. Mechanism, a gaseous hydrogen source is input into the air inlet, the gaseous hydride generation area is provided with elemental selenium or elemental sulfur, the hydrogen source ionization area is equipped with an electric heating wire, and the temperature of the gaseous hydride reaction area is controlled At 100-400°C, the temperature of the gaseous hydride generation zone is higher than the temperature of the gaseous hydride reaction zone. This online reaction device for generating gaseous hydride can improve safety and cost issues that previously required transportation and storage of hydrogen selenide or hydrogen sulfide.

Description

Technical field [0001] The present application relates to the field of selenization reaction, and in particular, to a selenization reaction device for generating hydrogen selenide online. Background technique [0002] The selenization (sulfidation) reaction is very critical for photovoltaic technologies such as copper indium gallium selenide. When elemental selenium (elementary sulfur) is used for selenization (sulfidation), a large number of selenium clusters (sulfur clusters) are easily formed and accumulated on the surface of the sample. Affects further selenization (sulfidation) of the sample. Using hydrogen selenide (hydrogen sulfide) to selenize (sulfide) the sample can effectively avoid the above problems. However, both hydrogen selenide and hydrogen sulfide gases are toxic, and the transportation and storage of these toxic gases are both safety and cost issues. Contents of the invention [0003] In order to improve the safety and cost issues during transportation...
