Study of a New Structural Photovoltaic Module

Abstract

The parallel arrangement of cells could reduce the current level in each string and hence decrease the series resistance loss and increase the module output power. The morphology of the cross-sections of separated cells by nondestructive cutting or infrared nanosecond laser cutting tech was comparatively characterized in this study. The obtained results demonstrate that the cross-section by non-destructive cutting tech was smooth and no nanocrack was found, which could benefit the module output power during the entire operating lifetime. Also, soft welding ribbons were employed in our study to replace the common conducting paste for the interconnection of separated cells. Modules assembled with this non-destructive cut cells can fully endure the simulated environmental tests.
