I-V measurement is very important for solar cell research well as for production. The probing method is often different between them, and that may create measurement errors. We have found that FF is normally measured lower in production line than in research environment, and the deviation gets bigger as the current grows and as the bus bar gets narrower. That means we need to know how the deviation is caused by the probing differences, particularly for high-efficiency cells. We have tried various probing patterns and analyzed the cause of the measurement errors. Using the results, we will propose better probing method in order to reduce the deviation between research and production environments. In addition to the information we already published in our previous paper, this paper has added more test results and new insight.
