Abstract

A photovoltaic cell manufacturing method includes: forming a photoelectric converter (12) including a plurality of compartment elements (21, 21s), the compartment elements (21, 21 s) adjacent to each other being electrically connected; determining the compartment element (21s) having a structural defect (R, A1, A2, A3) in the photoelectric converter (12); narrowing down a region (Z) in which the structural defect exists in the compartment element (21 s) based on a resistance distribution which is obtained by measuring resistances of a plurality of portions between the compartment elements (21, 21s) adjacent to each other, image-capturing the inside of the narrowed region (Z) in which the structural defect exists by use of an image capturing section (24), accurately determining a position of the structural defect from the obtained image so that a portion in which the structural defect exists in the compartment element (21s) is restricted; and removing the structural defect by irradiating the portion in which the structural defect exists with a laser beam.

Description

technical field [0001] The present invention relates to a method for manufacturing a solar cell and an apparatus for manufacturing a solar cell, and more specifically, to a method for manufacturing a solar cell and an apparatus for manufacturing a solar cell capable of detecting and repairing structural defects at low cost. Background technique [0002] From the viewpoint of efficient energy utilization, solar cells have been widely and widely used in recent years. In particular, solar cells using silicon single crystals are excellent in energy conversion efficiency per unit area. However, on the other hand, since solar cells using silicon single crystals use silicon wafers obtained by cutting silicon single crystal ingots, the production of ingots requires a lot of energy, resulting in high manufacturing costs. In particular, when realizing a large-area solar cell installed outdoors, it is currently very expensive to manufacture a solar cell using a silicon single crystal....
