As solar cells undergo rapid market expansion and production increases, a more stable supply of large volume materials is demanded. Solar cell manufacturing processes make heavy use of substances in liquid state at room temperature, which are then vaporized and injected into the manufacturing process. The vaporization system in this study makes use of bubbling and is able to heat and vaporize 100 L of liquid material by controlling the air bubble diameter to 1 mm during bubbling and by optimizing the heating configuration for the liquid. This paper introduces liquid vaporization technology and presents an explanation of the vaporization system together with experimental results.
