PURPOSE:To eliminate the need for connecting leads, equip a photovoltaic power generation element with an enlarged effective area, and to realize a high-efficiency module by a method wherein a single-body amorphous photovoltaic power generation element including a multiplicity of comb-type collecting electrodes is separated into individual pieces and the resultant photovoltaic power generation elements are piled one upon another. CONSTITUTION:An amorphous film 13 provided with a PIN junction is formed on a wide, lengthy stainless steel substrate 12 and, on the amorphous film 13, a transparent electrode film 14 is formed. Next, on the transparent electrode film 14, numerous comb-type collecting electrodes 15 are formed one after another at a prescribed interval along the direction of length, for the formation of a single-body amorphous photovoltaic power generation element 11. Further, the power generation element 11 is separated into individual amorphous photovoltaic power generation elements 11A, 11B, etc., each containing an electrode 15. Stacking is so accomplished that the electrode 15 of each of the separated power generation elements 11A, 11B, etc., may be in contact with a substrate 11 of a next power generation element 11. This results in an enlarged power generation element module effective area without using connecting leads. |
