摘要： 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.

摘要： A solar cell includes a first photoelectric conversion part, a second photoelectric conversion part, a first electrode, and a second electrode. The first photoelectric conversion part includes a photoelectric conversion layer containing a perovskite compound, a first transport layer, and a second transport layer. The second photoelectric conversion part is arranged below the second transport layer of the first photoelectric conversion part and has a different material or structure from the first photoelectric conversion part. The first electrode is electrically connected to the first photoelectric conversion part on one surface of the first photoelectric conversion part, and the second electrode is electrically connected to the second photoelectric conversion part below the second photoelectric conversion part. The first electrode has a stacking structure of at least two layers, and the second electrode is formed as a single layer.

摘要： A solar cell includes a tunneling layer located on one side of a semiconductor substrate, a first conductive region located on the tunneling layer, a first insulating film located on and passivating the first conductive region, a second conductive region located at the other side of the semiconductor substrate and composed of a doping region, a first electrode connected to the first conductive region, and a second electrode connected to the second conductive region. The first conductive region includes a first part connected to the first electrode and a second part other than the first part, and a thickness of the first part is different from that of the second part.
