A method for manufacturing a perovskite solar cell module encapsulated with a self-cleaning thin film by using inkjet printing, the method comprising:
- coating an outer surface of a perovskite solar cell with an organic film, an inorganic fil, or both;
- and
- forming a surface structure providing a self-cleaning function on the surface of the organic and/or inorganic film surrounding the perovskite solar cell,
- wherein the forming of the surface structure comprises:
- forming a boundary line by using an inkjet printing process on the surface of the organic and/or inorganic film surrounding the perovskite solar cell;
- and
- forming a micro lens by using an inkjet printing process on the surface of the organic and/or inorganic film surrounding the perovskite solar cell, the micro lens being surrounded by the boundary line.
