Abstract
Recently, commercial flexible silicon(Si) solar cells have been available for charging batteries and electronic devices. In this research, we present a methodology for determining the critical energy release rate at the EVA/Si cell interface of a flexible silicon solar cell, which can also be applied to other interfaces in solar cells. The outline of procedure is as follows:
•
Conduct a peeling test at the EVA/Si cell interface of the solar cell sample
•
Perform a tensile test on the upper layer of the solar cell sample
•
Execute IC Peel software
Inputs: Peeling force between EVA and Si layer, Young's modulus (E), Yield stress (σy), and Yield strain (εy) of the upper layer
Output: critical energy release rate (Gc) between EVA and the silicon (Si) layer
