VD0575 Selen (Se) Evaporative Materials

Description

Selenium evaporation materials, generally referred to as Se evaporation materials, are specific substances used to seal thin selenium films. These materials are designed to evaporate at controlled rates, thereby enabling the deposition of uniform and high‐quality coatings onto substrates such as glass, plastic or semiconductors.

The primary characteristics of the selenium evaporation materials include high purity, low vapour pressure and excellent thermal stability. The high level of purity ensures that the deposited films remain free from contaminants that could significantly reduce performance. The low vapour pressure permits precise control of the evaporation rate, which is essential for achieving thin and even films. The thermal stability ensures that the materials withstand the high temperatures required during evaporation without decomposing or oxidising.

Specification

Applications

Selenium evaporation materials are used for the manufacture of solar cells, optical coatings and thin‐film transistors. In solar cells, thin selenium layers serve as the active component that converts sunlight into electricity. In optical coatings, selenium films may adjust the reflective or transmissive properties of optical components. In thin‐film transistors, selenium films function as the semiconductor layer that regulates the electrical current.

The evaporation process is typically conducted within a vacuum chamber. A heated crucible or an electron beam is employed to evaporate the selenium evaporation materials. The vapour condenses on the substrate and forms a thin, uniform film.
