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 (σ_y), and Yield strain (ε_y) of the upper layer
Output: critical energy release rate (Gc) between EVA and the silicon (Si) layer

测定柔性硅太阳能电池 EVA/Si 电池界面的临界能量释放率。

最近，商用柔性硅（Si）太阳能电池已可用于为电池和电子设备充电。在这项研究中，我们提出了一种确定柔性硅太阳能电池 EVA/Si 电池界面临界能量释放率的方法，该方法也可应用于太阳能电池的其他界面。程序概要如下：-在太阳能电池样品的 EVA/Si 电池界面上进行剥离测试-在太阳能电池样品的上层进行拉伸测试-执行 IC Peel 软件输入：输出：EVA 和硅（Si）层之间的临界能量释放率（Gc）。
