Abstract: Proposed is a method for manufacturing a perovskite solar cell module encapsulated with a self-cleaning thin film by using an inkjet printing process. The method includes a boundary line forming step and a micro lens forming step. The boundary line forming step is to form boundary lines on the surface of an organic or inorganic film surrounding a perovskite solar cell array by an inkjet printing process, and the micro lens forming step is to form a micro lens array on the surface of the organic or inorganic film surrounding the perovskite solar cell array such that each of the micro lenses is surrounded by the boundary line. The boundary line is first formed to demarcate regions corresponding to the respective micro lenses, and the micro lenses are then formed in the regions surrounded by the boundary line, so that micro lenses with a high aspect ratio are densely formed.

Abstract: Disclosure is an ink supply system for an ink-jet head with a steam cleaning function. The ink supply system includes an ink-jet head including a nozzle, an ink storing device, a gas pressure control system applying negative or positive pressure to the ink storing device, a cleansing solution storing part, and a steam generating device changing at least a part of the cleansing solution into steam, wherein the cleansing solution or the cleansing solution steam is inserted into the ink storing device to clean the ink storing device and the ink-jet head.
The ink supply system cleans quickly and completely residue of ink to prevent contamination during the process of changing and using ink, and the ink storage, the ink-jet head, and the ink flow path are cleaned by evaporated cleansing solution during long-term printing, thereby maintaining the ink-jet head and the ink supply system into the initial state.
