Abstract: A method for manufacturing a solar cell includes: providing an electrode layer containing thermosetting resin on at least one of a first main surface and a second main surface, located opposite to the first main surface, of a photoelectric conversion unit; heating the electrode layer by irradiation of infrared light; and producing an air stream around the photoelectric conversion unit during irradiation of infrared light. The irradiation of infrared light may include irradiation of first infrared light from a first emitter facing the first main surface; and irradiation of second infrared light from a second emitter facing the second main surface.

Abstract: An solar cell is provided comprising a photoelectric conversion layer formed on a substrate formed of a semiconductor material, and a first finger electrode formed of printed conductive paste to a main surface side of the photoelectric conversion layer, wherein an average of standard deviations of heights of uneveness on a surface of the first finger electrode is 5.0 μm or less. The first finger electrode may be formed on a back surface side of the solar cell opposite to a light-receiving surface side. The substrate may be a crystalline silicon substrate. The photoelectric conversion layer may comprise the crystalline silicon substrate, an amorphous silicon layer formed on the substrate, and a transparent conductive oxide film formed on the amorphous silicon layer. The first finger electrode may be provided on the transparent conductive oxide film.
