A photovoltaic cell manufacturing method includes: detecting a structural defect existing in compartment elements; obtaining an image by capturing a region including the structural defect and the scribe line with a predetermined definition; specifying first number of pixels on the image, the first number of pixels corresponding to a distance between the scribe lines adjacent to each other or corresponding to a width of the scribe line; referring to an actual value indicating the distance between the scribe lines adjacent to each other or indicating the width of the scribe line, the distance being preliminarily stored, and the width of the scribe line being preliminarily stored; calculating an actual size of one pixel on the image by comparing the first number of pixels with the actual value; specifying second number of pixels on the image, the second number of pixels corresponding to the distance between the structural defect and the scribe line; comparing the second number of pixels with the actual size of one pixel, thereby calculating defect position information; and electrically separating the structural defect by irradiation with the laser light based on the defect position information. |
