Method for producing a crystalline silicon solar cell, a method of manufacturing a solar cell module, crystalline silicon solar cell and a solar cell module

In the present invention, high light incident surface conversion efficiency is to provide a method for producing a precisely machined crystalline silicon solar cells. A first transparent electrode layer forming step of forming a first transparent electrode layer 6, over substantially the entire surface of the second main surface side, wherein the back electrode layer forming step of forming a back surface electrode layer 11 composed mainly of copper , after the first transparent electrode layer forming step and the backside electrode layer forming step, at least a first transparent electrode layer 6 of the first main surface side, the second main surface side of at least a second transparent electrode layer 10 and the back surface electrode layer 11 perform insulation processing step of the short circuit of an insulating region 30 to be removed, the insulating treatment step, from the outer peripheral side surface of the one conductivity type monocrystalline silicon substrate 2 to a position within 3 mm, the first major surface from the side, with a step of irradiating a laser beam along the entire circumference of the first main surface outer peripheral portion.
