Method for manufacturing perovskite solar cell module encapsulated with self-cleaning thin film by using inkjet printing, and perovskite solar cell module with self-cleaning function manufactured thereby

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.
