What are the responsibilities of the assistant engineer of photovoltaic coating equipment?

repair related equipment. The assistant engineer of photovoltaic coating equipment is responsible for maintaining related equipment. Photovoltaic coating equipment often has line pipe failures, which require the maintenance of assistant engineers of photovoltaic coating equipment. Assistant engineer of photovoltaic coating equipment is a series of generators using parallel plate coating boat and high frequency plasma exciter. Under the condition of low pressure and rising temperature, the plasma generator is directly installed in the middle of the coating plate to react. The active gases used are silane and ammonia. These gases act on the silicon nitride stored on the silicon wafer. Different refractive indices can be obtained by changing the ratio of silane to ammonia. In the deposition process, a large number of hydrogen atoms and hydrogen ions are produced, which makes the hydrogen passivation of the wafer very good.
