The invention discloses a photoelectric material circulation barrel and a manufacturing process thereof. The photoelectric material circulation barrel comprises a closed barrel body, and a material in-out pipe for communicating the interior and the exterior of the barrel body is arranged at the upper end of the barrel body and provided with a valve; and the photoelectric material circulation barrel is characterized in that a content gauge and an air inlet pipe are further arranged at the upper end of the barrel body, the content gauge is inserted into the barrel body and is in sealed connection with the barrel body, the air inlet pipe is used for communicating the interior and the exterior of the barrel body and provided with a valve, the lower end of the material in-out pipe downwards extends to the bottom of the barrel body, and the surface roughness of the inner wall of the barrel body is lower than 0.2 micron. According to the photoelectric material circulation barrel, the air inlet pipe is used for injecting high pressure and high purity inert gas into the interior of the barrel body, a photoelectric material is pressed out from the material in-out pipe, and the degree of purity of the photoelectric material is kept; and meanwhile, the flow of the photoelectric material can be accurately controlled. The photoelectric material circulation barrel is manufactured through the seven main steps including component machining, mechanical grinding and polishing, ultrasonic cleaning, welding, electrochemical polishing, quality testing and assembling, and the product quality is actually improved.
