Abstract
A method for manufacturing a solar cell includes: forming a first photoelectric conversion part including a photoelectric conversion layer including a perovskite compound, a first transport layer, and a second transport layer; and forming a first electrode electrically connected to the first photoelectric conversion part and forming a second electrode electrically connected to the first photoelectric conversion part. The formation of the first photoelectric conversion part includes: forming a first film using a first material constituting the perovskite compound; spraying a second material constituting the perovskite compound on the first film to form a second film; performing a first heat treatment to diffuse the first film and the second film to form the perovskite compound; and performing washing to remove the residual second film residual on the perovskite compound.
