The invention discloses a method for manufacturing a double-layer solar energy printing screen. The method for manufacturing the double-layer solar energy printing screen comprises the steps that: S1: a first-layer solar energy screen is manufactured by laser or etching, wherein an opening graph of the solar energy screen is carved on a certain thickness of metal plate in a hollowing manner by utilizing a laser cutting process or an etching process; S2: the screen is preprocessed, wherein processing procedures of oil removing, acid washing, water scrubbing, and abrasive blasting are carried out on the metal plate obtained from the step S1; and S3: a second screen is manufactured by electroforming, wherein a photosensitive film layer is uniformly pasted on the surface of the metal plate, graphic areas are exposed and developed, and thus the photosensitive film of a non-graphics areas are removed, the developed metal plate is put in an electroforming groove to be electroformed, and then a film stripping and cleaning process is carried out, so that manufacture of the double-layer solar energy printing screen is accomplished. According to the double-layer solar energy printing screen provided by the invention, a smooth solar-battery electrode fine grid line can be printed, good current collection and transmission capability are achieved, and the solar energy conversion efficiency is improved effectively.
