Title:
SOLAR CELL MODULE MANUFACTURING METHOD, SOLAR CELL MODULE MANUFACTURING DEVICE, AND SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2019/150585
Kind Code:
A1
Abstract:
This solar cell module manufacturing method includes a first step for directing X-rays toward a region where a first metal component and a second metal component constituting a solar panel are soldered together, and acquiring an X-ray transmission image in a region where soldering is to be carried out, which is the region where the first metal component and the second metal component overlap in a direction parallel to the in-plane direction of the solar panel. This solar cell module manufacturing method also includes a second step for calculating, from the X-ray transmission image, the area ratio of a soldering portion where the first metal component and the second metal component are actually joined by soldering to the region where soldering is to be carried out in the direction parallel to the in-plane direction of the solar panel. This solar cell module manufacturing method also includes a third step for comparing the area ratio with a predefined determination standard to determine whether the solder joint state between the first metal component and the second metal component is good or not.
